Solving memory leaks using Flash builder 4 profiler
Locating memory leaks section in FB4 docs provides an overview and few techniques for handling this issue.
In this article I would like to offer another technique for using the object references view to quickly track down the root of a memory leak, straight down to the exact line of code causing it.
In short:
1. Choose a repeatable sequence.
2. Use the "Generate object allocation stack traces" checkbox when starting the profiling session.
3. Execute the sequence several times, and take a first memory snapshot. Execute it few times more and take a second snapshot.
4. Locate a class whose instances are not being GCed.
5. Open this class in the object references view for both snapshots.
6. Expand the first instance's back reference list, and look for suspicious path.
7. Starting from top to root, go through the path, and for each object compare its instance count for both snapshots.
The instance whose count is the same for both snapshots is causing the memory leak, and accumulates instances of the object it holds a reference to. it is a one-to-many-reference-holder.
8. By looking at the Allocation Trace view for the accumulated object, you can find where in the code the reference was added to it.
9. Make sure the reference is removed.
Details:
I assume you are already familiar with this view, and got to the point where you know which the object not being GCed is, and needs to find out who's preventing it from being released.
In an average application, after running a sequence of steps a few times, you may find yourself with hundreds of instances of the same class, each has hundreds of back references listed in the object references view, which can be quite overwhelming.
Where do you start? What should you look for?
You came to the right place! I will show you a very quick and simple way to spot the bug:
Before I start, there is an important concept you should get familiar with. I call it "the one to many reference holder".
The idea is quite simple, and is best visualized by an illustration:
Let's say you have a memory leak which results with 3 instances of the same object (class A) in the first snapshot, and 6 instances in the second snapshot (taken after repeating the same sequence of steps few more times) . A possible topology of these objects references may look like this in the first and second snapshots:
In the above illustration, all three instances are referenced by a single object (of class B), which is referenced up to the GC root.
Class B is a one–to-many-reference-holder,and is a good candidate for causing a memory leak. In case the number of class A instances keeps growing while you repeat the scenario, then class B has a memory leak.
Another possible reference topology may end up with the same result of 3 and 6 instances:
This time, the 3 instances are held by other 3 instances (class B), which in turn are held, again, by a single object (class C), which is held up to the root. In this topology, although class B does hold a reference to class A, we can clearly see that it is pointless to deal with it, since class C is the one accumulating references. He is a one-to-many-reference-holder and causes the memory leak. If we deal with class C, the class B instances along with class A instances are all gone.
Having this concept clear, answers the question "what do we look for?".
Although FB4 does not have this nice topology view for object references (Mihai Corlan kindly pointed me to Grant skinner's article on the flash sampler which might be used for allowing this kind of view), you'll see that finding these one-to-many-reference-holders is a matter of minutes. In the "object references" view, you open a suspected path to the object, and start following it to the root, checking the instance count of each object on this path.
Let's look on a real life sample:
Looking at this view(part of the namespaces is hidden for client's privacy sake), we see the following classes along this path:
DatagridItemRenderer, CoverageMetricRenderer, SummaryFooter, ConfigurableDataGrid, DataGridContent, ProfilerExtendedQueryResultWrapper , TransactionclassesProxy and so on.
We then go back to the Memory snapshot view, sort it by class name, and check the number of instances of each class (Instances column).
The following table summarizes the number instances of the above mentioned classes for two snapshots (the second taken after few more scenario repeats):
The picture become very clear now: ProfilerExtendedQueryResultWrapper remains with the same number of instances between snapshots, but the number of instances (of class DataGridContent) it holds, keeps growing.
This is our one-to-many-reference-holder !
Resolving this will clear this path from this point up.
Let's take a closer look at the suspected area:
From looking at the object references view, we can see that ProfilerExtendedQueryResultWrapper has a property named _entries, which is of type ArrayCollection. This property accumulates references to DataGridContent instances.
When you see the [savedThis] and [listener0] properties, it's an indication of reference made by adding event listeners, and should be read as follows:
One of DataGridContent's functions was added as an event handler to an event dispatched by _entries property of ProfilerExtendedQueryResultWrapper.
As a result, _entries holds a reference to DataGridContent instance through one of it's functions.
In case you are familiar with the code, it will probably take you few minutes to locate where exactly in the code does this happen.
However, FB4 can take you to the exact line of code, relieving you from the task of looking for it by yourself:
In order to let FB4 find the buggy line of code, you should check the "Generate object allocation stack traces" checkbox when starting the profiler session:
Turning this feature on, allows you to see where in the code was an instance created.
In this case, the instance of interest is the instance of the function added to the arrayCollection's list of event listeners.
Clicking on the "Function" row will show you it's allocation trace on the right "Allocation trace" pane. Clicking on the topmost line of this trace will open the code editor on the line where this function instance was created (line 99 in DataGridContent class):
Let's examine this code excerpt:
allResults = (value as IProfilerResult).entries; allResults.addEventListener(CollectionEvent.COLLECTION_CHANGE,handleCollectionChange)
We can see that handleCollectionChange function, which belongs to DataGridContent class, is being added as a handler to the collection change event of the entries property.
As it turns out, this event listener is not removed, and the entries property does not belong to a child of DataGridContent (adding an event listener to your child does not cause memory leaks due to the GC sweep mechanism).
This is our memory leak bug !
Resolving event listener memory leaks:
A memory leak caused by an event listener can be solved by one of these ways:
1. Take care of removing the event listener when it is no longer needed.
2. Use the useWeakReference parameter to create a weak event listener .
In our case changing the code to the following solved the problem:
allResults.addEventListener(CollectionEvent.COLLECTION_CHANGE,handleCollectionChange,false,0, true ); | https://www.tikalk.com/posts/2010/05/10/solving-memory-leaks-using-flash-builder-4-profiler/ | CC-MAIN-2018-34 | en | refinedweb |
Lambda Expressions in C++ 11 – Part 2 (Usage and Significance)
In the previous article – Lambda Expressions in C++ 11 – Part 1 (Definition and Syntax), we discussed the meaning of lambda expressions and their syntax. Here, we shall discuss the usage of lambda expressions and the reasons why they are so significant.
Usage and significance of Lambda Expressions
As mentioned in the previous article, lambda expressions are, in a way, anonymous functions. A typical lambda has a parameter list, a body and can return values. It has a [] (known as the Capture Clause) in place of the function name, which contains the list of variables that are to be captured explicitly by the lambda (either by reference or by value).
A typical lambda looks like:-
[capture_clause] (parameter_list) {body of the lambda}
[&x, &y] () {return x+y;}
Now, why exactly do we need lambdas? What role do they play in our programs?
The main use of lambdas is as a replacement for function objects. A lambda has a compact syntax and does not require us to define a class. Hence, it results in a better code that is easier to write and less prone to errors as compared to function objects.
A lambda implicitly defines a function object class and then constructs a function object of that class type.
For example, to count the no. of even numbers in a vector using a lambda expression, you would write the following program :
#include <iostream> #include <algorithm> #include <vector> using namespace std; int main() { vector<int> v; // Create a vector object for (int i = 1; i <= 5; ++i) // Add 5 members { v.push_back(i); } int num_even = 0; // num_even stores the total no. of even numbers in the vector // The following code counts the no. of even numbers in the vector for_each(v.begin(), v.end(), [&num_even](int n) { cout << n; if (n % 2 == 0) { cout << " is even " << endl; ++num_even; } else { cout << " is odd " << endl; } return 0; }); // Now, display the total no. of even numbers in the vector cout << "This vector contains " << num_even << " even numbers " << endl; getchar(); return 0; }
Output of this lambda example
1 is odd
2 is even
3 is odd
4 is even
5 is odd
This vector contains 2 even numbers
Creating the same program using a function object instead of lambda expression
#include <iostream> #include <algorithm> #include <vector> using namespace std; class func_class { func_class& operator=(const func_class&); int& cnum_even; public: explicit func_class(int& num_even) : cnum_even(num_even) {} void operator() (int n) const { cout << n; if (n % 2 == 0) { cout << " is even " << endl; ++cnum_even; } else { cout << " is odd " << endl; } } }; int main() { vector<int> v; for (int i = 1; i <= 5; ++i) { v.push_back (i); } int num_even = 0; for_each (v.begin(), v.end(), func_class (num_even)); cout << " This vector has " << num_even << " even numbers. " << endl; getchar(); return 0; }
Output of this function object example
1 is odd
2 is even
3 is odd
4 is even
5 is odd
This vector has 2 even numbers.
As is obvious from the two programs shown above, lambda expressions have significant advantages over function objects.
However, there is one downside to using lambda expressions. If the functionality that is required in the program is complex, lambdas make it difficult to manage code properly. Therefore, if the required functionality is large and complex, it would be better to use function objects rather than lambdas.

Code coverage is a multi-edged sword 🙂 There is no one right answer for how to do it and there are many ways to misuse it. Here I’ll talk about how to think about code coverage and then talk about what we do and reports we use to track it.
Let’s say your test pass rate is 99.9%. Is that good? Well, maybe. It’s not nearly enough information to know. Are the tests testing the primary user scenarios? Do you have enough tests? Are you missing testing on entire modules? Code coverage is one tool in the toolshed to help answer the question “Is that good?”
Code coverage data is collected while your tests are run (both automated and manual) and records what blocks in your code are covered (and not covered). It can be used in many scenarios:
- To determine what parts of your code are not getting covered and allow you to make intelligent decisions about whether or not to do additional testing to cover that code.
- To determine when you have too many tests – lots of tests that test basically the same code and don’t cover distinct scenarios.
- Combined with pass rate, defect rate and code churn info, help prioritize where do direct your testing efforts.
- Identify “dead” code that can never be called so it can be removed.
How much is enough?
Code coverage is often used as a metric to determine whether sufficient testing has been done to “release” software. The age old question is “How much is enough?” One size does not fit all. Except in the most extreme cases, 100% is not the right answer. Think about what would be involved in 100%. You’d have to write tests to execute every single exception handler, every single branch in your code. Your code probably includes machine generated code – for example, web service SOAP proxies that you don’t even use. There are other example of “dead” code that is hard or inadvisable to remove.
So, if it’s not 100%, what is it? We use a minimum bar of 70%, with the vast majority of that coming from automated tests. We only use manual testing coverage to bridge gaps in our automated testing. Would more be better? Maybe. One thing to keep in mind is that every automated test you have comes with a tax – you have to write it, run it and maintain it indefinitely (but this is the subject of a whole different blog post – so I’ll try to get to that one in the next few months).
Be careful how you use code coverage. No amount of code coverage will tell you if you have a well tested app. This is because there are tons of bugs that can’t be flagged by code coverage. The problem in these cases is not that the code isn’t being covered but rather that the data variation isn’t sufficient. Buffer overruns are a very simple example of bugs that can still exist in code that has 100% code coverage. This fact really hit me most as we were building TFS and I realized how susceptible SQL is to this problem. Running every query/stored procedure tells so little about the correctness of your SQL code. SQL depends so much on the data you have in the database and the values you query for.
I’ve seen teams drive for exceptionally high code coverage numbers. Like everything else in this world, the closer you want to get to “perfect”, the harder it is. It’s much easier to go from 20%->30% than from 60%->70% and even harder to go from 80%->90%. Grinding out test after test to cover every block of code becomes an exercise of increasing effort and decreasing return (in terms of useful bugs found). At some point you are better off directing that extra effort at alternative testing approaches. For us, we’ve decided 70% is the min bar. Making that the min bar, of course means that our average is a bit higher than that.
The DevDiv code coverage methodology
As I mentioned before, we focus primarily on automated testing code coverage. The reason is that we have to test on such a wide range of configurations, we must be able to rely on our automated tests to find the vast majority of problems. We break things down at the DLL/Assembly level and our metrics are based around the percentage of component that have 70% or better code coverage. Our primary report looks like this and shows % of components and the % code coverage of that component by coverage band, trended by build:
We classify each componentby % code coverage bands and track the trends over time. By the time we ship Orcas, the bar should be 100% green. Our goal for Beta 1 was 75% of components over 70% code coverage. Our goal for Beta 2 is 90% of components over 70% code coverage and our goal for RTM is 100% of components over 70% code coverage.
We then break that down by feature team and factor in the pass rate on each run. Obviously, it lots of tests are failing, it’s going to affect your coverage numbers.
And then we enumerate each of the binaries that are failing the 70% min bar and identify action plans for each.
Summary
Code coverage is a very useful tool in helping to spot areas of your code that need additional testing. Use it that way. Don’t be a slave to code coverage. Nothing replaces the value of having a person think through all of the scenarios the software supports and describing an appropriate test plan. The code coverage data is a tool to help you refine your test plan and identify areas you may not be thinking about.

You’re right on. Code coverage is a good metric to keep track of, but is just one piece of the pie. As for how much is enough, I have my teams strive to reach 90%, especially in areas deemed critical to the app. 100% coverage is usually unrealistic and trying to go from 90% – 100% coverage can be as time consuming as just getting to 90% in the first place. The Law of Diminishing Returns is definitely in effect there.

I want to do coverage on my native VC++ 6.0 source code. Any idea how I can go about without using VSTS.
I have been struggling to find out if VS6 or VS8 has some way of manually doing the coverage. I was also looking into the Profiler as an option.
Do you think I get some way out to do this without VSTS?
You can do code coverage on VC6 code using the VSTS code coverage tools. Here’a post on how to do it. Does this help?

How do I archive old branch in TFS 2010?
@Rajiv – We don't have a true "archive" feature for branches in TFS 2010. If you're looking to prevent people from making any further checkins to the branch, you can apply a check-in lock at the root of the branch. We have an item on our backlog tracking the request to add and archive feature for branches, and I would also suggest visiting our UserVoice site and adding your support to the existing feature suggestion: visualstudio.uservoice.com/…/2980353-allow-marking-a-branch-as-obsolete-or-locked-or-a-

I do not like the current patch's inclusion of a vague reference to corrupting client output in "some WSGI hosting solutions". This is text going into the page describing mod_python deployment, specifically. It should limit itself to what happens under mod_python. Sure, adding prints to stdout is a bad idea in other hosting environments too, but that's irrelevant to someone trying to figure out how to debug a problem under mod_python and more likely to cause confusion than anything else.

Terms
Here are terms used in the discussion of URL security zones.
- URL action. A browser action that can pose a security risk to the local computer.
- URL policy. A policy that determines which permission or trust level is set for a particular URL action.
- URL security zone. A group of URL namespaces that are assigned an equal level of permissions (or trust). Each URL action for the zone has an appropriate URL policy assigned to it that reflects the level of trust given to the URL namespaces in that zone.
- URL security zone template. A tool that allows users to specify levels of restriction using easy-to-understand terms: High, Medium-High, Medium, Medium-Low, and Low.
Security Zone Manager Extensibility.
Default URL Security Zones
The following sections describe the default URL security zones.
Local Intranet Zone.
Trusted Sites Zone.
Internet Zone
Use the Internet zone for Web sites on the Internet that do not belong to another zone. This default setting causes Windows Internet Explorer to prompt the user whenever potentially unsafe content is about to download. Note: Web sites that are not mapped into other zones automatically fall into this zone.
By default, the Internet zone uses the Medium Template.
In addition to the settings that the default template defines, there is a hidden setting, URLACTION_SHELL_WEBVIEW_VERB, which is set to URLPOLICY_ALLOW.
Restricted Sites Zone.
In addition to the settings that the default template defines, there is a hidden setting, URLACTION_SHELL_WEBVIEW_VERB, which is set to URLPOLICY_ALLOW.
Local Machine Zone.
URL Actions and Policies.
Aggregate URL Actions
The following table contains the aggregate URL actions and their aggregates.
URL Actions and Valid Policies
The following table contains the URL actions that the default URL security zone manager uses and the URL policies that you can assign to them. (URL actions that are new for Internet Explorer 7 appear at the bottom.)
Registry Keys
The registry stores the URL security zone settings in the following key.
HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion Internet Settings Zones
For Windows XP Service Pack 2 (SP2) and later, you can find the URL security lockdown zone settings in the registry in the following key.
HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER Software Microsoft Windows CurrentVersion Internet Settings Lockdown_Zones
You can determine the zones under which the Shell can open files (URLACTION_SHELL_EXECUTE_HIGHRISK) by checking the following registry values. These values correspond to the following zones, respectively: Local Machine zone, Local intranet, Trusted sites, Internet, Restricted sites.
HKEY_LOCAL_MACHINE Software Microsoft Windows CurrentVersion Internet Settings Zones 0 1806 1 1806 2 1806 3 1806 4 1806
If a URL policy value is
0x00, the action is allowed; if a value is
0x01, the user is prompted; and if a value is
0x03, the action is not allowed. For a list of possible URL policy values, see URL Policy Flags.
Security Warning: Setting these registry keys incorrectly can compromise the security of your application. The values for these registry keys are safe by default. By adjusting these values, you might put users at risk for an elevation of privilege attack. You should review Security Considerations: URL Security Zones API before continuing.

Let’s say there are two functions, Foo1 and Foo2. Foo2 needs
to be called after Foo1, and only Foo1 can call Foo2:
Foo1
Foo2
Foo2
Foo1
A realistic scenario might be when Foo1 is invoked using a
web service. Foo1 is called and needs to return as quickly as possible so that
the calling client doesn’t hang. This means both Foo1 and Foo2 must be asynchronous
functions, and that Foo2 must run after Foo1 has returned.
For Foo1 to be able to call Foo2 after Foo1 returns can be
done in multiple ways. One way might be to have external queue into which tasks
can be inserted so that they can be run when a certain state is set by a
separate thread. This is good for scalable enterprise architecture, but seems a
bit of an overkill when all we want to do is to call Foo2—after Foo1.
Another way is using the timer object. A third way is using
the relatively new ‘async’ method modifier.
The “async” function modifier was introduced in Visual Studio
2012/2013.
Before talking more about the async modifier, here is a complete listing of the code that is also attached to this tip. It's a console application:
using System;
namespace MyCSasync
{
using System.Threading;
using System.Threading.Tasks;
class MyClass
{
public static string[] Strings = new string[3];
public static int Count = 0;
private async Task Foo2()
{
await Task.Yield();
Strings[Count++] = "Foo2 called at " + DateTime.Now.Ticks;
}
public async Task Foo1()
{
Strings[Count++] = "Foo1 at " + DateTime.Now.Ticks;
// Call Foo2 asynchronously AND after this function returns.
Foo2();
Strings[Count++] = "End of Foo1 at " + DateTime.Now.Ticks;
}
}
class Program
{
static void Main(string[] args)
{
MyClass myclass = new MyClass();
myclass.Foo1();
while (MyClass.Count != 3) Thread.Sleep(1);
foreach (string msg in MyClass.Strings)
{
Console.WriteLine(msg);
}
}
}
}
While Foo1() is called asynchronously from the Main function, it could be called from a web service method which needs to return back to a client as quickly as possible so the client doesn't seem to hang. Foo2() is a private function that will need to be called after Foo1 completes.
Foo1()
Main
Foo2()
private
Foo2 is partially executed so that Foo1 can return. This partial execution is just
await Task.Yield()
This allows Foo2 to temporarily exit so that Foo1 can finish. The "Yield" method, as described by Microsoft, "creates an awaitable task that asynchronously yields back to the current context when awaited." That's exactly what we would like to do. There are other ways to do this. Using a delay. The problem with that approach is the behavior of the code may change depending on how fast your computer is. This is easy to test. If you use Task.Delay(1), which is 1 millisecond, it is more than enough to make the code above seem to be behaving the same. If you change the Delay parameter to a TimeSpan object with 1 tick, you may see that the code no longer works as expected.
Yield
Task.Delay(1)
Delay
TimeSpan
When you run the code above (ctrl-F5), you should see something similar to:
Foo2 is called after Foo1. Note the tick difference, about 20,000. On my machine, that's about 3200th of a second. So a delay of 1 second would seem to work, but certainly not 1 tick. As an exercise, change the code "await Task.Yield()" to "await Task.Delay(1)" and you'll likely see that Foo2 is called after Foo1. Now change it to "await Task.Delay(TimeSpan.FromTicks(1))". You will see that Foo2 is called before "End of Foo1". This is because Foo2's await took less time than Foo1 could return.
await Task.Yield()
await Task.Delay(1)
await Task.Delay(TimeSpan.FromTicks(1))
End of Foo1. | http://www.codeproject.com/Tips/768633/Function-A-Calling-Another-Function-B-After-A-Retu | CC-MAIN-2016-36 | en | refinedweb |
For a few years I used excellent shared memory IPC implementation by studio_ukc:.
While it is really fast, there are several drawbacks. Also, many members were routinely asking for the working code of that class - the one available for the download needs to be fixed (although some fixes are available in comments section).
I decided to go ahead and upload my own implementation based on the same idea, but with most of drawbacks eliminated. Please read original article before proceeding with this one.
So, what are advantages of my implementation compared to the original?
CSimpleIPC ipc;
ipc.createConnectionPoint(blockSize, blockCount, maxExpansions, preAllocate, minExpansionDistance);
As you can see, now block size and block count are function parameters, not template ones. But it's not all yet. The blockCount that you pass is in fact initial number of blocks. If value of maxExpansions is over 1, then this IPC will increase number of blocks-in-use when needed. For example, you can start with 256 blocks. When IPC will need to use more, it will allocate 256 more, and so on - as many times as you specify in maxExpansions. Obviously, value of maxExpansions cannot be less than 1. The last parameter - minExpansionDistance controls how expansion happen. Basically, once number of available blocks becomes less or equal to minExpansionDistance , expansion happens - if maxExpansions are not reached yet. You probably noticed one more parameter - preAllocate , but I will cover it later in the Tweaks section.
blockCount
maxExpansions
minExpansionDistance
preAllocate

So, for usage in your project you'll need only first 3 files.
Please excuse me for the code in IPCTest.cpp - it's quite crude and "not pretty", but it serves well for the purpose of testing and benchmarking. You can also look at it for usage example, but here is the general idea:
//start with:
CSimpleIPC ipcMain;
if (!ipcMain.createConnectionPoint(blockSize, blockCount, maxExpansions, preAlocate, minExpansionDistance))
//signal error, decide on what to do in case of failure;
// in some other place or thread:
CSimpleIPC ipcClient1, ipcClient2, .. ipcClientN;
if (!ipcClient1.attachToConnectionPoint(ipcMain.getConnectionPoint()))
//<signal error, ...>
....
if (!ipcClientN.attachToConnectionPoint(ipcMain.getConnectionPoint()))
//<signal error, ...>
// yet somewhere else - any thread:
while (!ipc.isCommunicationStopped()&& <some other condition>)
{
...
if(!ipcClientX.write(&somedata, sizeof(somedata)))
//<data was not written, do something>
...
if (!ipcClientY.read(&somedata, sizeof(somedata)))
//<data was not read, do something>
}
Now, to the important question: speed. Of course, extra features do not come for free. But how much is the degradation? I've tested free-flowing (i.e. just write/read, simplest processing) functionality on my desktop i7 3930 / 64Gb DDR3 1600 and my laptop - T7100 /4GB.
Numbers were pretty close - about 4.6 mln (laptop) and about 5.9 mln (desktop) blocks per second for the best case scenario, going down to 2.4 mln blocks per second (laptop) and ~1mln (desktop) in the worst case (on how to avoid it see Tweaks section). Here I specifically mention number of blocks transferred per second, rather then bytes. The most load for any implementation happens when block size is very small - few bytes. In this case the actual memory copy takes about 0.1% of overall processing time. But, the bigger are the blocks, the more time is spent in memcpy - up to 99.9%, so for larger blocks you are basically looking for the raw memory speed, and can say nothing about how well IPC is implemented.
Now, how this compares to the speed of original implementation by studio_ukc? I was quite surprised to see my implementation is about 50-60% faster on laptop and 30-40%faster on desktop (in the best case scenario) - kind of unexpected result, given that it's more complex. I included original implementation performance test as part of IPCTest.cpp, so you can compare results yourself.
Tweaks
Unfortunately, it is impossible to write an implementation that gives best results in all situations. So, there are several flags and values that you can set to tailor to your specific needs. Here is an explanation of what they are and when to use them:
doSingleThread
InterlockedIncrement
InterlockedDecrement
true
setMaxExpansionsCount()
So, when and why you need to use these flags? The fasted way to use this IPC is to use one instance of IPC per thread. Say, you create connection point in the main thread, and then in all working threads you create new IPC instance, connect it to that connection point and start sending/receiving data. Why not always use this scenario? Well, everything comes with price. In this case - too much memory. When you create IPC instance and connect it to connection point , it maps shared memory file into it's own memory space (to be exact, into memory space of that thread or process). So, if you allocated paltry 1Mb in one shared file, and then spawned 1000 threads, each of them using it's own IPC instance, then now your process(es) use 1Gb of memory. This is Not Good. But, if you can control number of threads/processes connected to the connection point, then you'd better use one IPC per thread.
Now, if above scenario is not possible, i.e. you can't predict/limit number of threads connected, or you want to use pretty large number of (blocks count*expansions count), then you need to try to retreat to the second line of defence: use preAllocate . Now, you can use just one IPC per process, and have all threads using it with almost same performance as if they had their own IPC instance. Yes, you pay for it with extra allocated space that might never be used, but 12K or even 120K is much less than potential gigabytes of memory that you suddenly need to allocate. In fact, I recommend setting this flag (and then using single IPC instance from all threads) in almost any situation - unless you either highly pressed on space usage (which is quite unlikely nowadays, especially under Windows ), or you need the top best performance, where even 1% counts. In general, using preAllocate and then accessing one instance from all threads is about 3-4% slower than having one IPC per thread.
Keep in mind, that if neither of these flags are set, i.e. you using default settings, performance is 4-5 times less than optimal, and fails to about 1 - 1.2 mln blocks per second for worst case scenario (single instance used by multiple threads). Interesting enough, performance of my desktop in this case is twice LESS than that of laptop.
setMaxSpinLocksCount(uint32_t blockAccessSpinLock, uint32_t expansionAccessSpinLock)
::Sleep(0)
blockAccessSpinLock
expansionAccessSpinLock
signleThread
And one more thing for advanced users Instead of calling "write" function that will copy passed buffer to the shared memory (to be read via copy again by "read" function), you can use 2 additional functions with the following use pattern:
BlockWriteDescriptor descriptor;
if (void* buf = ipc.acquireBlock(descriptor))
{
if (!(new (buf) MyType(<....>))))
//<Error. Mark this block somehow as unusable, i.e. zero it out>
ipc.releaseLockedBlock(descriptor);
}
//....
// somewhere else:
BlockReadDescriptor descriptor;
if (void* buf = ipc.acquireBlock(descriptor))
{
MyType* myVar = (MyType*)descriptor.result;
<... do someting with myVar ...>
myVar.~MyType();
ipc.releaseLockedBlock(descriptor);
}
Keep in mind, that all time between acquireBlock and releaseLockedBlock IPC might have other threads waiting, so use extreme caution and use this ability only if you know what you are doing. You might want to use it if you want to avoid memory fragmentation and save time on copying - this way you have only one memory manipulation (during call to "new") instead of 2 copies. But again - you were warned: this is extremely dangerous functionality, use with care.
acquireBlock
releaseLockedBlock
Also, this code is suited for VC++ 2010 and newer. If you want to use older compilers, please do the following:
#define uint32_t unsigned long
to_wstring
sprintf
That's it, and happy coding!
Updates: 07/15/2013: Version 1.1 - 2 bugfixes, both were prominent when INFINITE timeout was specified: 1) optional handle "stopOn" was ignored when INFINITE timeout was specified; 2) due to race conditions writer was not always informing reader that write operation was completed, thus causing reader to hang forever on the last unread block when INFINITE timeout was specified.

an information system that relates information sources and services through the use of hypertext-style relationships, creating a web of information that spans the Internet. Architecture defines the desired operational behavior of components within this information system, including software, machine, and human components, and protocols for interactions between components. The Web architecture is influenced by social requirements and software engineering principles, leading to design choices that constrain the behavior of the Web in order for the system to achieve desired properties: an efficient, scalable, shared information space that will continue to grow indefinitely across languages, cultures, and information mediums. This document is organized to reflect the three dimensions of Web architecture: identification, interaction, and representation.. This draft contains substantial revisions based on discussion at the TAG's 21-23 July face-to-face meeting in Vancouver...
A simple travel scenario is used throughout this document to illustrate typical behavior of Web components (e.g., servers, proxies, browsers, spiders, multimedia players, and other user agents -- programs acting on behalf of a person) and describe their interactions:'" in a glossy travel magazine. Dan has enough experience with the Web to recognize that "" is a URI. Given the context in which the URI appears, he can expect that it should allow him to access relevant weather information.
This scenario (elaborated on throughout the document) illustrates the three architectural divisions of the Web that are discussed in this document:".
Architecture defines the desired operational behavior of components within the system, including software, machine, and human components, and protocols for interactions between components. The Web architecture is influenced by social requirements and software engineering principles, leading to design choices that constrain the behavior of the Web in order for the system to achieve desired properties..
We assume readers are familiar with the rationale for some of the general design principles: minimal constraints (fewer rules make the system more flexible), modularity, minimum redundancy, extensibility, simplicity, and robustness.
This document focuses on the architecture of the Web. Other groups inside and outside W3C also document principles related to specialized aspects of Web architecture, including accessibility, internationalization, device independence, and Web Services. The section on Architectural Specifications includes some references.
This document is designed establish a shared vocabulary, i.e. a shared set of identifiers with agreed components.
Web components that reach conclusions based on comparisons done
through means other than those licensed by relevant specifications
take responsibility for any problems that result. For instance,
components should not assume that
"" and
"" identify the same
resource, since none of the specifications involved states that the
path part of an "http" URI is case-insensitive.; components components convey
information about a resource.
The more resource metadata is included in a URI, the more fragile the URI becomes (e.g., sensitive to changes in representation).
Editor's note: When finding available on URI opacity, link from here. See TAG issue metadataInURI-31. There is a related principle that has not yet been captured: don't restrict (e.g., through specifications) the URI space allotted to resource owners. See TAG issue siteDate-26: Web site metadata improving on robots.txt, w3c/p3p and favicon etc.
In the URI "", the
"http" that appears before the colon (":") is a URI scheme name.
The name refers to a URI scheme specification, which explains how
to assign identifiers within that scheme. The URI syntax is thus a
federated and extensible naming system wherein each scheme's
specification may further restrict the syntax and semantics of
identifiers within that scheme. Furthermore, the URI scheme
specification specifies how a component NOT introduce a new URI scheme when an existing scheme specifies the desired properties of identifiers and their relation to resources.

The URI that identifies the secondary resource consists of the URI of the primary resource with the additional identifying information as a fragment identifier. More precisely:

Resource descriptions: Owners of important resources SHOULD make available representations of. to a newsletter, posting to a list, or modifying a database.
Safe interactions are important because these are interactions where users can browse with confidence and where software programs (e.g., search engines and browsers that pre-cache data for the user) can follow links safely. Users (or components acting on their behalf) do not commit themselves to anything by querying a resource or following a link.
Principle
Safe retrieval: Components refers to the use of the same URI to refer to more than one distinct thing.
Good practice
URI ambiguity: Avoid URI ambiguity.
Ambiguous use of a URI can be costly. Suppose that one division of Large Company, Inc. maintains data about company Web pages, including who created them and when. Another division in the company maintains data about companies, including who created them and when. The second data set uses the URIs of the organization's home page as though it was the URI of the organization itself. When the two data sets are merged, the reuse of the URI causes information about companies to be merged with that of the home pages, resulting in potentially costly nonsense.
URI ambiguity differs from "indirect identification," which is
common. For example, one may identify meeting participants by using
their email addresses (e.g., "
[email protected]"). In
this case, all parties know that they are using a mailbox
identifier to indirectly identify the person. In terms of Web
architecture, "
mailto:[email protected]" still
identifies a mailbox, not a person.
As another example of URI ambiguity, saying that the URI
"" identifies "Moby Dick"
can lead to confusion because this might be interpreted as any one
of the following authority responsible for "weather.example.com" can offer Dan and Norm..
In the travel scenario, Dan
retrieves a representation from the weather site
"". He then follows
the link labeled "satellite image" in the representation data and
retrieves a representation of a secondary resource, a satellite
photo of the Oaxaca region.
The link to the satellite image is an HTML link encoded as
<a href="">satellite
image</a>. Dan (for example,
'Transfer-encoding: identity', which indicates that no compression
has been applied) are descriptive of the message. The remainder of
the headers and the message body together comprise a representation of the
resource identified by
"".
The browser reads the headers, learns from the 'Content-Type' field that the Internet Media Type of the representation data is "text/jpeg", reads the sequence of octets that comprises the representation data, and renders the image.
Dan decides to book a vacation to Oaxaca at "booking.example.com." He completes a series of HTML forms and is ultimately asked for credit card information to purchase the airline tickets. He provides this information in another HTML form. When he presses the "Purchase" button, his Dan wishes to change the state of the system by exchanging money for airline tickets.
The server reads the POST request, and after performing the booking transaction returns a message to Dan's browser that contains a representation of the results of Dan's request. The representation data is in HTML so that it can be saved or printed out for Dan's records. Note that neither the data transmitted with the POST nor the data received in the response necessarily correspond to any resource named by a URI.
Web components exchange information via messages that are constructed according to a non-exclusive set of messaging protocols (e.g., HTTP, FTP, NNTP, SMTP10, etc.). A message exchanged between Web components is an octet sequence consisting of:

Good practice
Link mechanisms: Format specification designers SHOULD provide mechanisms for identifying links to other resources and to portions of representations (via fragment identifiers). Allow Web-wide linking, not just internal document linking.
URI genericity: Format specification designers SHOULD allow authors to use URIs without constraining them to a limited set of URI schemes..
Many representations are encoded using data formats based on XML 1.0 [XML10]. This section discusses issues that are specific to such formats. Anyone seeking guidance in this area is urged to consult the "Guidelines For The Use of XML in IETF Protocols" [IETFXML], which [IETFXML]. authority responsible for "weather.example.com" realize that they can provide more interesting representations by creating instances that consist of elements defined in different published]."
Format specification designers that declare namespaces thus provide a global context for instances of the data format. Establishing this global context allows those instances (and portions thereof) to be re-used and combined in novel ways not yet imagined. Failure to provide a namespace makes such re-use technologies become widely deployed, this drawback will diminish in significance.
Dan receives a representation from "weather.example.com" in an unfamiliar data format. He knows enough about XML to recognize which XML namespace the elements belong to. Since the namespace is identified by a URI, he asks his browser to retrieve a representation of the namespace via that URI. He gets back some useful data that allows him to learn more about the data format; this is called a namespace document. Dan's browser may also be able to use machine-readable data automatically to perform useful tasks on Dan's behalf, such as download additional software components to process and render the format.
There are many reasons why a person or other component might want more information about the namespace. A person might want to:

These Internet Media Types create two problems: First, intermediaries in the Web are allowed to "transcode", i.e., convert one character encoding to another.

Second, representations whose Internet/" Internet Media Types effectively precludes

As we promised a few weeks ago, a BlackBerry® WebWorks™ SDK would be released soon that would have compatibility of applications moving forward. That day has arrived with the latest update to the BlackBerry 10 WebWorks SDK! Applications that are built with this BlackBerry WebWorks SDK will run on the latest delivered BlackBerry® 10 OS beta version as well as future OS updates.
Note that this does not mean that APIs don’t have the potential to change in the future, and there will certainly be more APIs added – but an application binary compiled with this SDK will continue to run on future OSes. With this guarantee, you can now build your BlackBerry WebWorks applications and submit them to the BlackBerry App World™ storefront for approval. You can now also apply for the Built For BlackBerry program before January 21st 2013 to take advantage of our 10k Developer Commitment to developers.
However, no BlackBerry WebWorks release would be complete without some new API additions. We have a ton of great stuff so let’s dive in.
Perhaps our biggest addition is the ability to integrate with the Calendar on the device. Create, edit, delete – it’s all there. It also delivers access to all calendars available on the device while of course respecting the work/personal boundary provided by BlackBerry Balance™. Combine this with the Contacts API delivered in the previous release for some very compelling applications that integrate with the BlackBerry 10 integrated PIM story.
Everyone likes toast (well, they should), and BlackBerry 10 has brought a mobile flavor to this breakfast staple with the Toasts notification concept. Toasts are quick, non-blocking notifications to the user that your application has performed some action, which are displayed for a minimal amount of time and then disappear. You can also enhance your toast with butter a button that allows the user to take some action in relation to that toast (eg. a toast that notifies the user that an item was deleted, and provides an Undo action). Check out blackberry.ui.toast for more on this one.
blackberry.ui.toast.show(“Pass the jam!”, options);
Now, wouldn’t it be cool if you could have a sensor in your phone that would tell you that your toast is ready before it was burnt? Well, no, we can’t do that (yet). But with this release of BlackBerry WebWorks, you now have access to a whole host of new sensor APIs. Orientation, light, proximity, compass, space-time disturbances; okay, not space-time, but yes on the rest. Leverage these APIs to add some real value into your application based on the device environment.
// Create a callback to handle each sensor function compassCallback(sensor, data) { alert("Current azimuth: " + data.value); } // Start listening to the compass sensor with a delay feedback of 1000 blackberry.sensors.setOptions("devicecompass", { delay : 1000 }); // Start the event listener for the sensors callback blackberry.event.addEventListener("devicecompass", compassCallback);
In the previous release of BlackBerry WebWorks, we provided a way to lock the orientation of your application by setting a flag in the config.xml. We have now provided a full JavaScript® API that allows you to lock/unlock your application dynamically based on your own logic. There are a few things to note with this change: To have a good JavaScript API signature, we are putting the orientation functionality right on the blackberry.app namespace, but this is out of line with the current config.xml approach of putting the parameter on the blackberry.app.orientation feature. So we have deprecated this, and now you should put orientation in config.xml on the blackberry.app feature. Also, if you do choose to set it in config.xml, that is a constant value that cannot be overwritten by the API – what you set in config.xml is what you get.
Speaking of config.xml, with this release we have all the pieces in place to allow for full localization of your application, including the display name of your application as well as the description. In the config.xml, you just need to put the localized text inside another element with the xml:lang attribute for the language. Furthermore, all of the built-in UI components are fully localized and reflect the current system language.
<widget xmlns=""> <name> The Ultimate Weather Widget </name> <name xml: insérez Françaises ici </name> </widget>
Let’s now take a look at some enhancements made to the underlying BlackBerry WebWorks platform. With this release, we have delivered a number of different optimizations to the runtime initialization process. Lots of highly technical, egghead type stuff. Long story short – your apps should load a whole bunch faster for your end users. Be sure to get the latest BlackBerry 10 OS build to see the full benefit.
Perhaps even more interesting is the addition of a child web view control. If you have a link in your content with target=”_blank” or use the window.open function, the content will now be loaded in a child web view that looks much like a card and won’t overwrite your current content. The user can then cancel the view to return to the originating page. When you use window.open, you will receive a window object for the child web view. One of the more obvious use cases here is a more seamless method of supporting OAuth for authentication into social networks like Facebook®, foursquare, Twitter®, and so on.
We have also added a new attribute to the element in config.xml that allows you to specify a single HTTP header key-value pair. This HTTP header will be added to every HTTP request sent from your application. This allows your backend system to key off of this header and perform any required customized processing for your app.
<widget rim:header=”header:Goooallll!”>
If that wasn’t enough on its own, we have also added a few new tooling features that should make your life a lot easier. First on deck is the ability to pass your application’s root folder into the bbwp tool to package your application. No more requirement to first zip your application content and risk feeling silly when you forget to update your zip file with your latest changes. The packager also supports ignoring folders and files within your application folder hierarchy; just create a “.bbwpignore” file in the root folder and list the folders and files you don’t want to be part of your application packager. The format of this file is essentially the same as the .gitignore file, with one or two very small differences.
Another potential time saver and headache reliever is a new facility that will allow you to forget about ever needing to update the version of the webworks.js file you reference in your app. In your application files, reference the webworks.js file like so:
<script src=”local:///chrome/webworks.js”>
The packager tool will include the latest webworks.js into your package and put it at the appropriate location to be loaded.
So there you have it. It is worth reiterating that with this release you can now submit your apps to BlackBerry App World and be assured they will run properly come launch of BlackBerry 10! So submit early so you can get your application approved, and then apply for the Built For BlackBerry program before January 21st, 2013. No time to waste – grab the SDK today! | http://devblog.blackberry.com/2012/11/blackberry-10-webworks-sdk-updated/ | CC-MAIN-2016-36 | en | refinedweb |
This article shows a solution to the problem of programmatically attaching delegate handlers to an object's events.
While building a prototype for an application framework, I came across a situation where I was creating a host process for multiple plug-in components. In the end-user implementation of these plug-ins, they would be exposing events to the rest of the framework. I wanted to provide both the option of tight-coupling to these events (manually adding handlers via += new ...) and loose-coupling to these events (through a publish/subscribe event-bus mechanism).
I wanted to make the publishing of events as transparent as possible to the plug-in developers without having to dictate too much of their implementation. I decided I wanted to be able to support transparent publishing of events to the event bus for any plug-in that decorated its events with a particular attribute (PubEventAttribute).
PubEventAttribute
I wanted plug-in implementers to simply decorate their classes as shown:
public class MyClass
{
...
[PubEvent]
public event Action<int> Event1;
}
The loading of the plug-ins in my framework would use reflection at initialization time to inspect the plug-in's instance for this attribute on its events. When an event with this attribute is discovered, a delegate would be programmatically attached to the event that would publish the results of the event onto an event bus.
All of this elegant designing on my part hit a road-block once I realized I had no idea how to generate a delegate for some arbitrary event. I realized I could narrow down the supported events to a specific type by limiting them to the Action<...> generic classes.
Action<...>
By narrowing down the format of the supported events, it occurred to me that I could simply match the Action<...> events to precompiled handlers that were themselves generic classes (called ActionPublisher<...>) that expose a public method matching the signature of the event.
ActionPublisher<...>
public
Using the single parameter version of Action<...> as an example, I created a matching class:
public class ActionPublisher<T>
{
public ActionPublisher( object sender, string topic )
{
_sender = sender;
_topic = topic;
}
private object _sender;
private string _topic;
public void PublishAction( T t )
{
Program.HandleEvent( new object[] { t } );
}
}
Querying an instance of a class for its events is as simple as:
MyClass c = new MyClass();
foreach( EventInfo e in c.GetType().GetEvents() )
{
foreach( object o in e.GetCustomAttributes( true ) )
{
if( o is PubEventAttribute )
{
...
}
}
}
Creating a delegate from some arbitrary type definition can be done using the Delegate class' static method CreateDelegate. The definition of the particular overload I'm using is:
Delegate
static
CreateDelegate
public static Delegate CreateDelegate(
Type type,
Object firstArgument,
MethodInfo method
)
The reason for using this particular delegate is because my specific application is for an embedded solution running on WinCE, and this is the only overload of CreateDelegate that is supported on WinCE.
The type argument is the type of the delegate being created. This should match the type of the event itself (EventInfo.EventHandlerType). The next argument is the instance that implements the delegate you want to connect to the event, which in our case will be an instance of our ActionPublisher<...> class. The final argument is of the type MethodInfo that describes the public method of the ActionPublisher<...> class that will be called when the event is fired (PublishAction in this case).
type
EventInfo.EventHandlerType
MethodInfo
PublishAction
The next problem to solve is creating an instance of the ActionPublisher<...> that matches our event type. This requires the ability to instantiate a generic type through reflection. Fortunately, I already wrote an article on this very topic. However, this method requires that I have an array of types describing the generic types of the generic class. Getting this information from the EventInfo class is non-intuitive, but I discovered it to be accessible from EventInfo.EventHandlerType.GetMethod( "Invoke" ).GetParameters() . This call actually returns us an array of ParameterInfo objects describing the generic arguments of the Action event. From this, I can instantiate a matching instance of the ActionPublisher class as follows:
EventInfo
EventInfo.EventHandlerType.GetMethod( "Invoke" ).GetParameters()
ParameterInfo
Action
ActionPublisher
Type publisherType = typeof( ActionPublisher<> ).MakeGenericType
( new Type[] { actionArgs[ 0 ].ParameterType } );
object publisher = Activator.CreateInstance( publisherType, c, "/Topic" );
Finally, adding the handler to the event can be done using the EventInfo class's AddEventHandler method. This method takes two arguments: the instance of the object implementing the callback and the delegate we just created. The full code is:
EventInfo
AddEventHandler
ParameterInfo[] actionArgs = eInfo.EventHandlerType.GetMethod
( "Invoke" ).GetParameters();
if( actionArgs.Length == 1 )
{
// create the ActionPublisher instance that matches our event
Type publisherType = typeof( ActionPublisher<> ).MakeGenericType
( new Type[] { actionArgs[ 0 ].ParameterType } );
object publisher = Activator.CreateInstance( publisherType, c, "/Topic" );
// create a delegate to the PublishAction method of the publisher
MethodInfo publisherInvoke = publisherType.GetMethod( "PublishAction" );
Delegate d = Delegate.CreateDelegate
( eInfo.EventHandlerType, publisher, publisherInvoke );
// wire up the delegate to the event
eInfo.AddEventHandler( c, d );
break;
}
The included sample application performs all of these steps for a class that exposes a single event of type Action<int>. This event is decorated with the PubEvent attribute and so gets a dynamically instantiated instance of ActionPublisher<int> added to it. Calling the method DoIt() fires the event. From this, we can see that our dynamically created delegate handler is invoked.
Action<int>
PubEvent
ActionPublisher<int>

Introduction
This article is a detailed guide to the UML Profile Authoring support in the IBM® Rational® Software Architect (RSA) and IBM® Rational® Software Modeler (RSM) 6.x products. It covers both the UI support and programmatic support (for users extending the tool itself). It mainly targets profile authors, but it also offers some insight into profile usage.
The covered versions (in chronological order as they were released) are 6.0 GA, iFix002, iFix003, 6.0.0.1 and 6.0.1. The 6.0.1 version is forward-looking -- it has not been officially released at the time this article was written. It is clearly indicated where there is a difference in behavior between versions.
The article assumes that you have reasonable knowledge of the UML 2.0 specification, especially the part related to Profiles. It does not attempt to further describe or clarify the specification, but rather focuses on its implementation in RSA and RSM. General knowledge about Eclipse, RSA, and RSM will be useful as well. Eclipse PDE (plug-in development environment subproject) knowledge is required if you wish to create plug-in based profiles.
Creating a profile
This section covers how to create a profile and its content. It also explores various features available to you in regard to the profile definition.
RSA and RSM UML Profiles are files with the .epx extension. The tool provides creating and editing capabilities only for files that are in the workspace. However, after you create a profile it does not necessarily have to be in the workspace to be used in models that are in the workspace -- more on this in the Deployment section below.
RSA and RSM also support Eclipse's open source profile.uml2 format for the purpose of applying it to a UML Model. It does not directly support editing files in this format, although they could be edited by using the open source's editor.
The rest of this article focuses on RSA and RSM's native profile format (.epx). For more details on the Eclipse’s open source format please see the Resources section.
The Modeling perspective is the best equipped for profile authoring. The two main views used in profile authoring are the Model Explorer and the Properties view. The Model Explorer is used to build the elements of the profile and the Properties View is used to set their properties.
Profile
You can create a new profile either by launching the New UML Profile wizard (shown in Figure 1) or the New UML Profile Project wizard. To launch the New UML Profile wizard, click File -> New -> Other and then Modeling -> UML Extensibility -> UML Profile.
Figure 1. New UML Profile wizard
The New UML Profile wizard creates a profile in the specified folder. The name of the profile does not have to match the name of the file containing it, although it probably simplifies things if they are the same. The model libraries could be imported during the profile creation but that could be done afterwards as well.
The New UML Profile Project wizard simply provides a shortcut to create a project and a profile in it at the same time. Please note that the profile does not have to be stored in Profile Project -- it could be placed in any project.
After the profile is created, it will be selected in the Model Explorer. Also, Figure 2 shows the Profile Editor associated with the .epx file that will open.
Figure 2. Profile Editor
The Profile Editor is associated with the .epx file itself. It only offers some informational data about the profile: profile name, file location (full path) and size, the time when the file was last modified, and whether or not the file is editable.
Please notice the (uml2) and the (UML2) entries under the profile in the Model Explorer. The (uml2) entry represents the imported UML 2.0 meta-model, which is the one being extended by the profile. The (UML2) entry represents imported UML2 Types model library. That is optional; the profile author does not have to import it.
Note: Theoretically, UML profiles could extend various meta-models, although the RSM and RSA implementation supports only the UML 2.0 meta-model.
The profile's properties (see Figure 3) are displayed in the Properties view when the profile entry (the item right below the profile file in the Model Explorer) is selected. Version- and Release-related properties are explained later (in the Change management section--see below). The Visibility property does not have any impact on your ability to apply the profile.
Figure 3. Profile properties
To add UML elements to the profile, select it in the Model Explorer, right-click it and click Add UML, as shown in Figure 4. The only UML types that can be created in a profile are Stereotypes, Classes, and Enumerations.
Figure 4. Add UML menu for profiles
Naming
The names of certain element types (Stereotype, Class, Enumeration, and Attribute) have to be valid Java™ identifiers. The most common violation of this rule is using the space character in the name. Depending on the exact profile structure, invalid names can cause various problems. The most serious problem is caused by invalid attribute names, which can corrupt the model where the profile is applied. With version 6.0 iFix002 and later, model corruption is prevented and in version 6.0.1 the tool does not allow invalid names to be entered in the first place.
Version 6.0.0.1 has problems with Enumeration Literals whose names are not a valid Java identifier: basically, those literals cannot be used. The versions prior to 6.0.0.1 (GA/iFix002/iFix003) and after (6.0.1) do not have such problems with the literals.
Stereotypes
To create a stereotype, select the profile in the Model Explorer and right-click it, then click Add UML -> Stereotype on the context menu. This results in the view shown in Figure 5.
Figure 5. Stereotype properties
A stereotype can be used simply to mark up the element to which it is applied. However, its real power is in the extension mechanism, through which it can actually modify the metaclass definition of one or more metaclasses. This extension is not automatically propagated to all instances of the metaclass (metaclasses); the stereotype first has to be applied to the modeling element that is an instance of the particular metaclass. Of course, you can make the extension required, in which case it is automatic -- for the model where the profile is applied.
Abstract stereotypes cannot be applied to modeling elements. The abstract stereotype can be specialized by another stereotype (more on this in the Generalization section).
The Leaf and Visibility fields are mostly ignored. Stereotypes marked as Leaf -- or with Visibility values other than the default (public) -- do not exercise any special behavior, although the stereotypes with the protected or package visibility are reported as errors when the profile is validated. You are discouraged from changing the default values for these two fields, since it is very likely that some sort of behavior will be associated with them in subsequent releases.
The Icon and Shape Image fields are covered in the Presentation subsection, and the Category field is covered in the Stereotype attributes subsection.
The metaclasses being extended by the stereotype are specified on the Extensions tab in the Properties view. The Metaclass Extensions table lists all existing extensions for the stereotype, as shown in Figure 6.
Figure 6. Metaclass Extensions
You can add a new extension by clicking the Add Extension button, which starts the Create Metaclass Extension dialog shown in Figure 7. The metaclasses available for extension are those defined by the UML 2.0 meta-model. Each extension can be marked as required or not (not required is the default). That flag can be set only when the extension is created. If it has to be changed, you must first remove the old extension and then create a new one.
When an extension is required it means that the stereotype will be applied automatically to all modeling elements that are instances of that metaclass, given that the profile owning the stereotype is applied to the model. If the extension is not required then the stereotype has to be applied to the element either through a user gesture or programmatically.
Figure 7. Create Metaclass Extension dialog
An attribute with a name in the base$<metaclass name> format is created in the stereotype for each metaclass that the stereotype extends. Those attributes are used by the system and should not be modified.
Please note that the stereotype can be applied only to the elements whose metaclass it extends. Of course, the profile (that owns the stereotype) itself has to be applied to the element's package hierarchy (most likely to the model itself) first.
The main aspects in which a stereotype can modify the metaclass definition are:
- Presentation
- Additional properties
- Additional constraints
Each of these is discussed in a separate section.
Presentation
When a stereotype is applied to a modeling element it can affect its presentation in multiple ways. The most obvious way is that the system now displays (by default) the stereotype name in guillemets in the front of the element's name, where appropriate (for example, in Model Explorer or on diagrams). For example, if a stereotype S is applied to the element E, the system will display <<S>> E in Model Explorer and on diagrams for that element.
Note: The tool does not automatically make the first character of the stereotype name lower-case for display purposes, as suggested by the UML 2.0 specification (see the Resources section). The name is displayed as is. However, the profile author can fully control the display name -- separately from the name -- using the localization mechanism (more on this in the Localization section).
A stereotype can have an icon and a shape image attached to it -- please see the General tab in the Properties view for stereotypes. Next to the Icon and Shape Image field on the General tab are two buttons: Browse and Clear. The Browse button lets you find an image file in the file system to be associated with the stereotype. The Clear button removes the specified image from the stereotype. Supported formats are BMP, GIF, JPG, and PNG for both Icon and Shape Image fields. Shape Image additionally supports files in the SVG format. Of course, neither image has to be specified -- it is entirely up to the profile author.
When a stereotype is applied to an element, the system will consult the preference settings to determine how to present the element. To invoke the preferences, click Window -> Preferences.
For Model Explorer, click Modeling -> Views. The Stereotype Style combo box in the Model Explorer settings group offers the following choices: None, Text and Decoration. None tells Model Explorer to ignore the applied stereotypes. Text means that all applied stereotypes will be listed in the guillemets in the front of the element’s name. Decoration tells Model Explorer to use the image from the Icon field of the applied stereotype. If none of the applied stereotypes has a defined icon, it defaults back to display stereotype names. Please note that if multiple applied stereotypes have defined icons, only one of them will be used.
Diagrams settings can be found in two places: by clicking Modeling -> Connectors for connectors and Modeling -> Shapes for shapes. The Stereotype style combo-box for connectors has only two options: None and Text. The shapes provide more choices: None, Text, Decoration, Decoration and Text, and Shape Image. Decoration displays the icon next to the element name -- the same as for Model Explorer, only one icon is used even when multiple applied stereotypes provide an icon. The difference is that it does not default back to stereotype name if there is no icon. Decoration and Text displays both the icon and the stereotype names, while the Shape Image option replaces the whole shape with the image specified in the stereotype.
Another interesting presentation feature for stereotypes is the Suppressed flag (found on the General tab in the Properties view). When set, it turns off the presentation capabilities of the stereotype: even if the stereotype is applied to an element neither the Model Explorer nor diagrams display any information about it. This is most useful when the intent is to use the stereotypes programmatically, to hold information or mark up elements but not to change the element’s presentation. The suppressed stereotypes can still be seen as applied in the Properties View’s Stereotypes tab for the element, unless even that is turned off through the preference settings (Window -> Preferences -> Modeling -> Views -> Properties View settings -> Show suppressed properties). The suppressed stereotypes can be applied only programmatically (they do not show up on the list of the applicable stereotypes), but they can be removed manually.
The version 6.0 iFix002 introduced an exception to this rule: suppressed stereotypes with the taggedValueSet keyword can be applied manually as well. This keyword can be set by selecting the stereotype in the Model Explorer and then going to the Stereotypes tab in the Properties view.
Stereotype attributes
Stereotype owned attributes are added to the metaclass definition as its properties, for the element instance where the stereotype is applied. For example, let's say that there is a stereotype S which extends the metaclass Actor and has an attribute named attr1. When this stereotype is applied to an actor in a model, the actor's set of properties will now include attr1 (in addition to all properties specified in the Actor metaclass, like name, visibility, and so on.)
To create a stereotype attribute, select the stereotype in Model Explorer, right-click it and click Add UML -> Attribute, as shown in Figure 8.
Figure 8. Attribute properties
The most important properties for an attribute (in addition to the name) are Type, Default Value, Multiplicity, and Unique.
Since the stereotype-owned attributes eventually become extended metaclass properties, their type cannot be just anything -- it has to be a type recognized by the system, for which it can provide proper handling of these properties. Supported types are:
- Primitive types from the imported model libraries
- Enumerations defined in the profile itself
- Classes defined in the profile itself
Attribute must have a type. If it is not specified, the tool will ignore that attribute when determining the stereotype-contributed properties for the element where the stereotype is applied.
The default value does not have to be specified -- in that case the tool will use its own default depending on the type. For example, the default for a String typed attribute is blank string.
The multiplicity indicates if the property will be treated as a singular value or a collection (multiplicity greater than 1). When the multiplicity indicates a collection, the user should also pay attention to the Unique field to indicate if the elements in the collection have to be unique or not. By default, this flag is set to require uniqueness.
Note: The multiplicity cannot be set in RSA versions GA/iFix002/iFix003 using the General tab (even though the field is visible there) -- you are forced to use the Advanced tab. This is not the case in RSA versions 6.0.0.1 and 6.0.1, nor in RSM.
The stereotype-contributed properties are displayed in the Properties view for the element to which the stereotype is applied, together with other properties. They can be found in two places: the Advanced tab and the Stereotypes tab (the Stereotype Properties table). In either case they are grouped together under the category named the same as the stereotype contributing the properties. You can override that rule: there is the Category field on the stereotype's General tab. If that value is specified then it will be used to group that stereotype's properties together instead of the stereotype name. An example when this is useful is when all stereotypes coming from the same profile need to group properties together under the same category.
Model libraries
Profiles support only 3 predefined model libraries: UML2 Types, Java Types, and Ecore Types. In order to use the types defined in one of those libraries, the library first has to be imported into the profile. The libraries can be imported when the profile is created through the New Profile wizard (by default it sets UML2 Types to be imported, but you can change that). They can also be imported at any other point by using the context menu in Model Explorer. Just select the profile and right-click it, then click Import Model Libraries.
The UML2 Types model library contains the 4 primitive types defined by the UML 2.0 specification (again, see the Resources section for more information on UML 2.0): Boolean, String, Integer, and Unlimited Natural. The Java Types model library defines primitive types corresponding to the Java language primitive types, and the Ecore Types model library defines primitive types corresponding to the Eclipse's EMF types.
UML2 and Java types are fully supported. The Ecore types are partially supported: they can all be specified, and the tool will provide read capability for all of them. However, it supports editing capability only for the types that have a direct Java type representation. For example, the tool provides editing capability for attributes whose type is EByte, but only the read capability for those whose type is ETreeIterator. It is envisioned that such types (like ETreeIterator) will be used only in conjunction with some sort of programmatic manipulation of the profile at the runtime.
Figure 9. Selecting attribute type
Enumerations
Enumerations can be used to specify the type of stereotype attributes only if they are defined in the same profile as the stereotype itself. The values for attributes whose type is an enumeration would be enumeration literals owned by that enumeration.
The profile-owned enumerations are not generally available outside of the profile itself.
Classes
Classes can be used to specify the type of stereotype attributes only if they are defined in the same profile as the stereotype itself. Any such class can (and should) have attributes of its own. The rules for those attributes (in terms of supported types and default values) are the same as for the stereotype attributes.
The tool only partially supports stereotype attributes of a class type. Such attributes can be specified, and the tool offers the read capability. However, it does not provide any UI to manipulate such properties. So, typing stereotype attributes with a class type is useful only in conjunction with some sort of programmatic manipulation of the profile at runtime.
The default value of an attribute typed as a class is null or empty collection (when the multiplicity is greater than 1).
The profile-owned classes are not generally available outside of the profile itself.
Generalization
A stereotype can specialize or generalize only another stereotype: a class cannot participate in the generalization relationship with the stereotype. The tool will let you specify generalization between the stereotype and a class but the validation of the profile will fail.
To specify a generalization relationship between the two stereotypes, select the stereotype that you wish to be the specialization in the Model Explorer and go to the Advanced tab in the Properties View. Select the Collections property and click the … button in the value field, as shown in Figure 10.
Figure 10. Stereotype collections property
This launches the Properties dialog. Select the Generalization collection and in the top right corner select the insert tool (the Generalization icon), as shown in Figure 11. Select the other stereotype and click OK.
Figure 11. Generalization collection
Profile constraints
In a profile only stereotypes can own constraints. To create a constraint, select the stereotype in the Model Explorer, right-click it, and click Add UML -> Constraint. The constraint can be named, but it does not have to be. It is a good idea to provide the name, though, since the name could be used in reporting the constraint failure by the tool.
It extends the meta-model to constrain the model where the stereotype is applied. The system automatically extends the meta-model if the specified language is supported. If the language is not supported, the constraint is ignored by the tool.
The constraint is defined in the profile but evaluated in the model, where the stereotype (that owns it) is applied.
The properties on the General tab (in the Properties view) are Name, Language, and Body, as shown in Figure 12. The two system-supported languages are OCL (Object Constraint Language) and Java. The content of the Body field depends on the specified language.
The Java-based constraints should yield better performance, might be easier to use to express complex constraints, and offer greater flexibility. On the other hand, the Java-based constraints work only with the plug-in deployed profiles (please see the Deployment section) and are more time-consuming for initial tests performed by you.
Figure 12. General constraint properties
Important properties on the Advanced tab (in the Properties view shown in Figure 13) are Evaluation Mode, Message Key and Severity. They are grouped under the Metamodel Constraint category.
The Evaluation Mode value could be either Batch (evaluated only on demand when you invoke the validation action) or Live (evaluated both when the change occurs and on demand). The default is Batch.
The Message Key is used to for display purposes when the constraint fails. If it is not specified, the system uses the fully qualified constraint name. If it is specified, the system looks it up in the corresponding properties file if there is one (more on this in the Localization section). If no properties file is found, the key itself is used. The single quote in the message must be escaped with another single quote.
The Severity could be Error, Warning, and Informational. The exact behavior for each of those values would depend on your preference settings. However, if a Live constraint with the Error severity is violated, the change is automatically rolled back.
Figure 13. Advanced constraint properties
Built-in OCL support
Note: This article does not attempt to clarify or explain OCL. The readers of this section should be familiar with the OCL specification (see Resources).
The supported version of the OCL is 2.0, matching the supported UML definition (2.0).
The OCL statement is entered in the Body field of the constraint's General tab in the Properties view.
The union of the user modeled stereotype and intersection of its meta-model extensions is used as the OCL context when the constraint is defined.
For example:
- Stereotype S1 has two attributes (a1: Integer, and a2 : Boolean), extends Class and Actor metaclasses, and has constraint profileCons1.
- OCL statement in the profileCons1 constraint would have access to properties a1 and a2 and intersection of features defined in metaclasses Class and Actor.
- The intersection of features defined in all extended metaclasses is used instead of the union to ensure that the constraint is syntactically valid, regardless of the element where the stereotype will be applied. The tool does not allow Class-specific features to be used in the constraint because the constraint would not be syntactically valid when the stereotype is applied to an Actor, and the other way around.
The element with the constraint's stereotype applied to it is used as the OCL context during the evaluation of the constraint.
For example:
- Actor A1 has stereotype S1 applied to it.
- The constraint profileCons1 is evaluated depending on the evaluation mode settings. At that time, actor A1 is used as the OCL context in the meta-model mode.
The UI provides syntax highlighting, content assist, and syntax parsing.
The constraint is evaluated during model validation in the model where the stereotype is applied. It is checked only for syntactical validity when the profile itself is validated.
If the constraint has a message associated with it (through the Message Id), the {0} variable in the message is substituted by the context element -- unless it is between single quotes.
Built-in Java support
The user can specify the Java class in the Body field of the constraint's General tab in the Properties view.
The Java class has to be specified using its fully qualified name. It has to extend the com.ibm.xtools.emf.validation.AbstractModelConstraint class. Both profile and the Java class have to be deployed through the same plug-in (more on this in the Deployment section).
The element with the constraint's stereotype applied to it is used as the constraint context during evaluation of the constraint.
The constraint is evaluated during model validation in the model where the stereotype is applied. It is not checked when the profile itself is validated.
If the constraint has a message associated with it (through the Message Id), it can be obtained from the IValidationContext object that is passed to the constraint by the system. The constraint can then deal with any number of the {n} variables in the message using standard Java message formatting.
Using UML profiles
The intent of this section is to provide a short overview of using UML profiles, so that you can quickly start testing the new profile. More advanced topics are covered later in other sections.
Applying profiles
Before the content of a profile (for all practical purposes, that means stereotypes) can be used in a model, the profile itself has to be applied to the model. To be precise, the profile can be applied to any package in the model, including the model itself. When the profile is applied to the model itself, it is visible in the whole model. If it is applied to some package in the model, then it is visible only in that package's sub-tree. It is usually easier to manage if the profile is applied to the model, but it is entirely up to you.
To apply a profile, select the model (package) in Model Explorer or on a diagram (if it is present there) and navigate to the Profiles tab in the Properties view, as shown in Figure 14.
Figure 14. Profiles tab
The Applied Profiles table lists all the profiles that have already been applied. Don't worry too much about the Version and Release Label columns for now, those concepts are covered later on in the Change management section.
To unapply (remove) a profile, select the profile and click the Remove Profile button.
Note: Not all profiles can be removed. There are certain profiles that are required by the system and the user cannot remove them. Three of those are Basic, Intermediate and Complete. These profiles are defined by the UML 2.0 specification. The other two (Default and Deployment) are defined by RSM and RSA.
To apply (add) a new profile, simply click Add Profile, which will lunch the Select Profile dialog shown in Figure 15.
Figure 15. Select Profile dialog
You can either choose one of the available (system-known) deployed profiles, or browse the file system to select a profile. More details on deploying profiles can be found later in the Deployment section. For now, the simplest way to start is to select the File option and then browse the file system to find the profile in the workspace.
Applying stereotypes
To apply a stereotype, select the modeling element in Model Explorer or on a diagram, and navigate to the Stereotypes tab in the Properties View, as shown in Figure 16.
Figure 16. Stereotypes tab
The Applied Stereotypes table lists all of the stereotypes that have already been applied. The Stereotype Properties table lists the element’s properties that are contributed by those stereotypes.
To unapply (remove) a stereotype, select the stereotype (s) and click the Remove Stereotypes button. If the stereotype is required (as indicated by the Required column) then it cannot be removed. To apply (add) a new stereotype, simply click Add Stereotypes, which will launch the Apply Stereotypes dialog shown in Figure 17.
Figure 17. Apply Stereotypes dialog
The list in the dialog contains all applicable stereotypes for that element that are not already applied. is being used.’s UML definition is linked to the model indirectly through the version.
Only the latest version completely and accurately reflects the UML definition of the profile. All other versions only hold enough information to enable the smooth transition of a model -- with that version applied to it -- to the newest version of the profile. And that is assuming there were no incompatible changes made between the versions (more on this topic in the Compatibility rules section).
To see the current (latest) version number of the profile, select it in the Model Explorer and navigate to the General tab in the Properties View. It has a read-only Version field.
To compare it with the version that is actually applied to the model, select the model in the Model Explorer and navigate to the Profiles tab in the Properties View. One of the rows will represent the profile of interest (if it is actually applied), and there is a Version column in the table.
Releasing a profile
Releasing a profile creates a special version of the profile. It is invoked through the context menu shown in Figure 18: select the profile in the Model Explorer, right-click it and click Release. This launches the Release Profile dialog (Figure 19), where you can specify the release label that will be associated with the released version. The release label is completely arbitrary: it is any string you wish to enter.
Figure 18. Releasing a profile
Figure 19. Release Profile dialog
Figure 20 shows how all released versions of the profile are listed in the Releases field on the General tab in the Properties View.
Figure 20. Released profile
If the most recent version is released, then the Release Label field displays the label associated with it. If the profile has not ever been released, or if it has been modified since the last release, then the Release Label field will indicate that.
In addition to creating a new profile version (and marking it with the release label), all non-released versions are removed. Consequently, non-released versions of the profile should be applied only to test models. The models with intermediate profile versions applied will be able to migrate to the released version, but they will lose data: applied stereotypes and values of stereotype contributed properties., let's say that you create a profile with one stereotype (S1) and then release it. You then add another stereotype (S2) to the profile. The tool would let you delete (or rename) S2 but not S1.
The compatibility rules are implemented through a live constraint: from the Preferences -> Window menu, click Modeling -> Validation -> Constraints. Next, click either UML 2.0 -> Modeling -> Profiles or UML 2.0 -> Model Quality Dimensions -> Compatibility. Finally, select the Profile Compatibility Restrictions constraint.
If you must make a change that would be incompatible with a released version, for whatever reason, then there is a back door of temporarily disabling this constraint. Of course, it is strongly recommended not to go this route, but in case it is absolutely necessary the back door is there. However, be warned that in this case it is most likely that there will be data loss during profile migration.
Migration
Migration upgrades the applied profile version in the model. It upgrades the model model, 21, if the system detects that an older version of the profile is applied, it will prompt you to perform the migration. Of course, you may decline.
Figure 21. Profile migration warning
However, if the profile file does not have the previously applied version anymore, another dialog will precede the Profile Migration warning: the Unrecognized Schema error dialog shown in Figure 22.
Figure 22. Unrecognized Schema error
The most likely reason that a profile file would not contain the version is that you have either released or compressed the profile (more on those concepts in separate sections), and the old version was an intermediate version. The cause of the warning is that the profile extends the meta-model and the tool does not know how to treat certain data in the model file, since the schema defining them is missing.
The tool is not even aware that the cause is a missing profile version at this point. If you choose to ignore the unrecognized content, the model will be opened in a special mode. At this point, if the warning was caused by a missing profile version, the system will offer the profile migration. Please note that the regular migration rules still apply; since the profile file does not contain the old version, the applied stereotypes (and the values of properties contributed by them) will be lost.
Another cause of this warning might be that the profile is missing altogether. In that case, even if you open the model by ignoring the unrecognized content, the tool will simply inform you that a particular profile is missing: there will be no way to migrate.
In either case, when a model with unrecognized content is opened in the special mode and the changes are made to it, you are prompted to discard or keep this information during the save operation, as shown in Figure 23.
Figure 23. at any time from the Properties view (for the selected package). To perform the migration, select the package (model) to which the profile is applied in the Model Explorer and navigate to the Profiles tab in the Properties view, as shown in Figure 24.
The table lists all applied profiles, and any profile that is out of sync is clearly marked as such. The Migrate Profile button is used to perform actual migration.
Figure 24. Manual profile migration
Compressing a profile
It is possible to purge intermediate (non-released) versions without releasing the profile. To do so, select the profile in the Model Explorer, right-click it and click Compress. It will delete all non-released versions except the last one. If the profile is dirty, then it will first create a non-released version, then save it and keep both the version it created as well as the last non-released version before that one.
This action is useful when there is a prolonged development of the profile. Since a new version is created every time the profile is saved, its size can grow quickly, which can significantly affect performance both in terms of memory usage and speed.
The Compress menu item has been introduced in the 6.0.1 version of RSM and RSA. don. In some cases the tool will store a fully qualified path (prior to the 6.0.1 version) or a relative path (6.0.1 and later) highly recommended that the location containing the profiles is pointed to by a path-map. To create a path-map, click Window -> Preferences, then click Modeling -> Path Maps. The result is shown in Figure 25.
Note: This list displays only user-defined path maps; it does not display tool-defined path maps.
Figure 25. Path maps
Click the New button to create a new path-map, opening the dialog shown in Figure 26. Again, the name is arbitrary – it is up to you to determine the naming convention. The location (folder) should point to the folder that will contain the profile.
Figure 26. New Path Map dialog
If the model and the applied profiles are shared, then the same path-map has to be created on every system where they are used. The tool will not enforce the existence or validity of the path map: it is up to your particular team to ensure that the path maps exist and point to valid locations. If the path map does not exist or is not valid, the model simply will not open properly since the tool will be unable to find the applied profile (please see the Change management section for details).
Please note that the profile author cannot ensure path map. The profile author has an option to prevent the profile from showing up in this list (more on this later).
Another useful feature is that the profile author can define the path map the profile author and the actual design. The author might create the plug-in with the sole purpose of deploying the profile, or the profile could be added to an existing plug-in where it will be just on of many artifacts. There could be code accompanying the profile, providing runtime manipulation of models where the profile is applied (again, if required). recommended for the user-created profiles as well.
Note:This is a convention only. It is not required nor enforced. There is only one exception to this related to the localization in the 6.0 GA version (more on this in the Localization section)..
Here is an example of the content of the build.properties file (it assumes that the profiles are in the profiles folder):
bin.includes = plugin.xml,\ plugin.properties,\ <some file>,\ profiles/,\ <some file>
The row defining the profile location is in bold font.
Dependencies
The plug-in hosting the profile will need dependencies to the com.ibm.xtools.emf.msl and com.ibm.xtools.uml2.msl plug-ins. If the profile is going to use Java-based constraints, it will also need a dependency to the com.ibm.xtools.emf.validation plug-in.
Registering a path map
Regardless of the location in the plug-in where the profile is stored, there should be a path map defined for that location. The path map can be registered through the plugin.xml file of the plug-in.
Here is an example:
<extension id="somePathmapExtensionId" name="somePathmapExtensionName" point="com.ibm.xtools.emf.msl.Pathmaps"> <pathmap name="MY_SAMPLE_PROFILES" path="profiles"> </pathmap> </extension>
The extension point is com.ibm.xtools.emf.msl.Pathmaps. The extension's id and name are up to you. map pointing to a location in another plug-in. In that case, the pathmap element has another attribute: plugin. The value of the plugin attribute is the name of the referenced plug-in, without the version information. Here is an example:
<extension id="somePathmapExtensionId2" name="somePathmapExtensionName2" point="com.ibm.xtools.emf.msl.Pathmaps"> <pathmap name="MY_SAMPLE_PROFILES_2" plugin="com.mycompany.myproduct.myplugin" path="profiles"> </pathmap> </extension>
Registering a profile
The profile itself is also registered through the plugin.xml file. Here is an example using the path map
MY_SAMPLE_PROFILES from the previous section, and 3 profiles (MyProfileA, MyProfileB, and MyProfileC) deployed in the profiles subfolder of the plug-in:
<extension name="someProfileExtensioName" point="com.ibm.xtools.uml2"> </UMLProfile> </extension>
The extension point is
com.ibm.xtools.uml2.msl.UMLProfiles. The extension's id and name are up to you. The UMLProfile element applying profiles. The value is used as is unless it is preceded with a percentage sign (%). The percentage sign indicates that the name is localized and will be retrieved from the plugin.properties file, using the remainder of the value as the key in the properties file (the standard Eclipse behavior for providing localized strings in the plugin.xml -- read more about Eclipse in the Resources section). So, in this example the name for MyProfileB is defined in the plugin.xml (MyProfileB) while the names for MyProfileA and MyProfileC are defined in the plugin.properties file using the specified keys (MyProfileA.name and MyProfileC.name, respectively).
You can specify the path in a number of different formats but it is strongly recommended to use the path map format. In this example, all 3 profiles use path maps, although it might not seem so at first glance. The paths for MyProfileA and MyProfileB are specified relative to the plug-in's root (profiles/MyProfileA.epx and profiles/MyProfileB.epx). However, the folder profiles are covered by the
MY_SAMPLE_PROFILES path map, so the tool will automatically use the path map. The registration for MyProfileC is even more explicit: it states the path map directly (pathmap://MY_SAMPLE_PROFILES/MyProfileC.epx).
The required flag should not be used. offered in the list of deployed profiles when applying profiles. The default is
false. The value obviously depends on the intent: if the profile should be applied only programmatically, then the value should be
false, otherwise it should be
true.
Using the New Plug-in Project wizard and Plug-in editor
The New Plug-in Project wizard and the Plug-in editor are Eclipse concepts, so for more details on this topic please see the Resources section. The only profile-specific information is the exact extensions for registering path maps 27.
Note: To use the plug-in development capabilities, the Eclipse Plug-in Development capability has to be enabled. To do so, click Window -> Preferences, then click Workbench -> Capabilities, then click Eclipse Developer and select the Eclipse Plug-in Development capability.
Figure 27. New project
The values for the fields in the wizard (Figure 28) 28. New Plug-in Project wizard
The next step is to create a folder in the plug-in to hold profile(s). map and the profile in the plugin.xml you need to launch the Plug-in editor. Simply double-click on the plugin.xml file and the editor will be started, as shown in Figure 29.
Note: While you will do most of the work with the profile in the Modeling perspective, the modification of the plugin.xml file is easier done through some other perspectives, like Resource and Java perspective. Of course, nothing stops you from opening the proper view (for example, the Navigator view from the Basic category) in the Modeling perspective and using it to navigate to the plugin.xml file (Model Explorer does not display those files).
Figure 29. Navigator and the Plug-in editor
To work in the text mode, simply go to the plugin.xmland the build.properties tabs of the Plug-in editor. The syntax is the same as used in examples from the previous few sections. However, you may wish to take advantage of the more advanced features of the Plug-in editor.
The dependencies can be specified on the Dependencies tab shown in Figure 30, and in the Plug-In Selection window in Figure 31.
Figure 30. Dependencies tab
Figure 31. Select plug-in for dependency
You can register the path map and the profile through the Extensions tab.
Figure 32. Extensions tab
Also, make sure on the Build tab (Figure 33) that the folder containing the profile is included in the binary build.
Figure 33. Build tab
Once the plug-in is ready for deployment, the you can export it using Eclipse's plug-in exporter. To invoke the exporter shown in Figure 34, select the desired plug-in(s) in the Navigator view, then click File -> Export. Select the Deployable plug-ins and fragments entry from the list.
Figure 34. Export plug-in wizard
Of course, the plug-in could be part of a bigger application that has its own way of packaging plug-ins.
Open-source UML2 format
RSM and RSA also support the open-source UML2 format to a certain degree. The profiles in the uml2 format (the file naming convention is <profile name>.profile.uml2) can be directly applied to models in RSM and RSA (*.emx). Both file system deployment and plug-in deployment could be used. RSM and RSA also provide export and import functionality to and from the uml2 format.
For more details on the open source UML2 format please see the Resources section.
Export
To invoke the Export wizard, click File -> Export -> UML2 Model. The wizard -- shown in Figure 35 -- will create a *.profile.uml2 file in the specified location.
Note: The file will have the IDs regenerated. That is, the wizard cannot be used if you plan to maintain the RSM or RSA version (*.epx), make changes there, and re-export it on a regular basis. In this case, the exported file will always have different IDs, so the models where it is applied would not migrate correctly. The wizard is more of a one-time operation, which you would use if you intend to convert your model to the UML2 format (from the .epx) and then continue maintenance in that format.
Figure 35. Export wizard
Import
The import functionality is very similar to the export – it just works in the opposite direction. To invoke the Import wizard, click File -> Import -> UML2 Model. The wizard will create a *.profile.epx file in the specified location.
Note: As with the export, do not use the Import wizard if you plan to maintain the UML2 version, make changes there, and re-import on a regular basis. Rather, use it if you intend to convert the model to the .epx format and continue maintenance in that format.
Localization
Profiles use :: sequences replaced by double underscores (__). Any space characters are escaped (using the \ character). The IDs for stereotype categories and constraint messages are those strings themselves.
Figure 36 presents an example.
Figure 36. Example profile structure for localization
The stereotype S1 has a category MyCategory. Its constraint has a message ID MyMsgId. Also, please notice space in the name of the enumeration literal L 1. Here is the content of a corresponding
RSM and RSA can pre-populate the localization file. The action is invoked from the context. Also, the localization file has extension *.properties and as such is not visible in the Model Explorer. To view it you have to use some other view (like Navigator)..
RSM and RSA mostly do not publicly expose its API for profile and stereotype support. However, there are a few classes that are exposed that would make life easier when you maps for its location.
To use these APIs the plug-in will need dependencies on various other plug-ins. Please see the Deployment section for details about how to create a plug-in dependency.
RSM and RSA Specific APIs
UMLModeler
The UMLModeler class can be used to obtain the profile. It is provided by the com.ibm.xtools.modeler plug-in.
The following example obtains the MyProfileA profile from the location specified by the MY_SAMPLE_PROFILES path-map. If the profile is not already loaded, this code forces loading (the Boolean parameter of the
getResource method) – assuming that the path provided in the URI constructor is right.
import java.util.List; import org.eclipse.emf.common.util.URI; import org.eclipse.emf.ecore.resource.Resource; import org.eclipse.uml2.Profile; import com.ibm.xtools.modeler.
AbstractModelConstraint
Profile constraints implemented as Java classes have to extend this class. It is provided by the com.ibm.xtools.emf.validation plug-in.
The method to override is:
public IStatus validate(IValidationContext arg0)
The argument (
arg0) can be used to return the status. The IValidationContext interface defines the
createFailureStatus and
createSuccessStatus methods.
Open Source API
For the full documentation for the open source the reader in the right direction in the terms of needed APIs.
All of the classes listed in this chapter are provided by the org.eclipse.uml2 plug-in.
org.eclipse.uml2.Package
EList getAppliedProfiles(); public Set getAllAppliedProfiles(); public boolean isApplied(Profile profile); public String getAppliedVersion(Profile profile); public void apply(Profile profile); public void unapply(Profile profile);

Best Practices
The following is a list of recommended practices:
- Avoid using special characters (like a space) in your profile. If the special characters are needed for display purposes, use localization mechanism. Version 6.0.1 prevents you from using special characters altogether anyway (except for the enumeration literals).
- Keep profiles and models in separate locations. If possible at all, keep them on a separate change management life cycle.
- Always use path maps, regardless of the deployment type (file system vs.. If you are using the 6.0.1 version, use the Compress option to reduce the size of the profile. If you have some older versions, the only recourse is to release the profile from time to time, but be aware about plug-in profile, create a path map with the same name pointing to the same location in both the development (IDE) and the runtime (target) environment. Preferably, the path map would be defined as a user path map (through the Preferences) in the development environment and in the plugin.xml file of the plug-in for the runtime environment. That way, the models can be easily shared between the two environments.
Known issues
The following is a list of profile-specific known issues. It does not list other general issues in RSM and RSA although they could (and often do) affect profiles as well. For those, please consult the release notes of the particular RSM or RSA version.
- Naming problems. For more details, please see the Naming sub-section of the Profile Creation section.
- OCL constraints do not support properly defined profile enumerations.
- Only partial support for attributes of a class type.
- There could be migration problems between non-released versions.
- The tool prevents a profile from being applied to a package if it is already applied to one of the package’s ancestors, including the model. However, it lets the user do the opposite (that is, apply the profile to one of the package’s ancestors even if it is already applied to the package. That may lead to problems, especially when profile migration is involved.
- The iFix002 and iFix003 versions unload non-RSM or RSA resources under certain conditions. This behavior affects the whole application, including profiles. Examples of non-RSM or RSA resources are the UML 2.0 meta-model and various model libraries. When that happens, the only way around is to restart the application.
Final word
UML profiles enable you to extend the UML meta-model for different purposes. In essence, that means the tool's behavior is extended as well. RSM and RSA offer extensive UI to build and use profiles. They can range from simple profiles providing some additional presentation functionality to the complex profiles deployed through plug-ins and with accompanying code taking advantage of the profile's meta-model extensions.

System-Level Fault Tolerant Measures
Topic Last Modified: 2006-08-16
This section provides system-level considerations and strategies for increasing the fault tolerance of your Exchange 2003 organization. Specifically, system-level refers to your Exchange 2003 infrastructure and the recommended best practices for implementing fault tolerance within that infrastructure.
The following figure illustrates a reliable Exchange 2003 infrastructure and lists the best practices for maintaining a high level of fault tolerance.
System-level fault tolerant measures
This section discusses methods for designing fault tolerance at each level in your Exchange 2003 infrastructure. Specifically, this section provides information about:
Implementing firewalls and perimeter networks
Ensuring reliable access to Active Directory and Domain Name System (DNS)
Ensuring reliable access to Exchange front-end servers
Configuring Exchange protocol virtual servers
Implementing a reliable back-end storage solution
Implementing a server clustering solution
Implementing a monitoring strategy
Implementing a disaster recovery strategy
It is recommended that your Exchange 2003 topology includes a perimeter network and front-end and back-end server architecture. The following figure illustrates this topology, including the additional security provided by an advanced reverse-proxy server (in this case, Internet Security and Acceleration (ISA) Server 2000 Feature Pack 1).
Exchange 2003 topology using a perimeter network
Deploying ISA Server 2000 Feature Pack 1 in a perimeter network is just one way you can help secure your messaging system. Other methods include using transport-level security such as Internet Protocol security (IPSec) or Secure Sockets Layer (SSL).
For complete information about designing a secure Exchange topology, see "Planning Your Infrastructure" in Planning an Exchange Server 2003 Messaging System.
For information about using ISA Server 2000 with Exchange 2003, see Using ISA Server 2000 with Exchange Server 2003.
Exchange relies heavily on Active Directory and Domain Name System (DNS). To provide reliable and efficient access to Active Directory and DNS, make sure that your domain controllers, global catalog servers, and DNS servers are well protected from possible failures.
A domain controller is a server that hosts a domain database and performs authentication services that are required for clients to log on and access Exchange. (Users must be able to be authenticated by either Exchange or Windows.) Exchange 2003 relies on domain controllers for system and server configuration information. In Windows Server 2003, the domain database is part of the Active Directory database. In a Windows Server 2003 domain forest, Active Directory information is replicated between domain controllers that also host a copy of the forest configuration and schema containers.
A domain controller can assume numerous roles within an Active Directory infrastructure: a global catalog server, an operations master, or a simple domain controller.
A global catalog server is a domain controller that hosts the global catalog. A global catalog server is required for logon because it contains information about universal group membership. This membership grants or denies user access to resources. If a global catalog server cannot be contacted, a user's universal membership cannot be determined and logon access is denied.
At least one global catalog server must be installed in each domain that contains Exchange servers.
Because domain controllers contain essential Active Directory information, make sure that the domain controllers in your organization are well protected from possible failures.
The following are best practices for deploying and configuring Active Directory domain controllers and global catalog servers:
Unless it is a requirement for your organization, do not run Exchange 2003 on your domain controllers. For information about the implications of running Exchange on a domain controller, see "Running Exchange 2003 on a Domain Controller" later in this topic.
Place at least two domain controllers in each Active Directory site. If a domain controller is not available within a site, Exchange will look for another domain controller. This is especially important if the other domain controllers in your organization can be accessed only across a WAN. This circumstance could cause performance issues and possibly introduce a single point of failure.
Place at least two global catalog servers in each Active Directory site. If a global catalog server is not available within a site, Exchange will look for another global catalog server. This is especially important if the other global catalog servers in your organization can be accessed only across a WAN. This circumstance could cause performance issues and possibly introduce a single point of failure.
There should generally be a 4:1 ratio of Exchange processors to global catalog server processors, assuming the processors are similar models and speeds. However, higher global catalog server usage, a large Active Directory database, or large distribution lists can necessitate more global catalog servers.
In branch offices that service more than 10 users, one global catalog server must be installed in each location that contains Exchange servers. However, for redundancy purposes, deploying two global catalog servers is ideal. If a physical site does not have two global catalog servers, you can configure existing domain controllers as global catalog servers.
If your architecture includes multiple subnets per site, you can add additional availability by ensuring that you have at least one domain controller and one global catalog server per subnet. As a result, even if a router fails, you can still access the domain controller access.
Ensure that the server assigned to the infrastructure master role is not a global catalog server. For information about the infrastructure master role, see the topic "Global catalog and infrastructure master" in Windows 2000 Server Help.
Consider monitoring the LDAP latency on all Exchange 2003 domain controllers. For information about monitoring Exchange, see Implementing Software Monitoring and Error-Detection Tools.
Consider increasing the LDAP threads from 20 to 40, depending on your requirements. For information about tuning Exchange, see the Exchange Server 2003 Performance and Scalability Guide.
Ensure that you have a solid backup plan for your domain controllers.
As a best practice, you should not run Exchange 2003 on servers that also function as Windows domain controllers. Instead, you should configure Exchange servers and Windows domain controllers separately.
However, if your organization requires that you run Exchange 2003 on a domain controller, consider the following limitations:
If you run Exchange 2003 on a domain controller, it uses only that domain controller. As a result, if the domain controller fails, Exchange cannot fail over to another domain controller.
If your Exchange servers also perform domain controller tasks in addition to serving Exchange client computers, those servers may experience performance degradation during heavy user loads.
If you run Exchange 2003 on a domain controller, your Active Directory and Exchange administrators may experience an overlap of security and disaster recovery responsibilities.
Exchange 2003 servers that are also domain controllers cannot be part of a Windows cluster. Specifically, Exchange 2003 does not support clustered Exchange 2003 servers that coexist with Active Directory servers. For example, because Exchange administrators who can log on to the local server have physical console access to the domain controller, they can potentially elevate their permissions in Active Directory.
If your server is the only domain controller in your messaging system, it must also be a global catalog server.
If you run Exchange 2003 on a domain controller, avoid using the /3GB switch. If you use this switch, the Exchange cache may monopolize system memory. Additionally, because the number of user connections should be low, the /3GB switch should not be required.
Because all services run under LocalSystem, there is a greater risk of exposure if there is a security bug. For example, if Exchange 2003 is running on a domain controller, an Active Directory bug that allows an attacker to access Active Directory would also allow access to Exchange.
A domain controller that is running Exchange 2003 takes a considerable amount of time to restart or shut down. (approximately 10 minutes or longer). This is because services related to Active Directory (for example, Lsass.exe) shut down before Exchange services, thereby causing Exchange services to fail repeatedly while searching for Active Directory services. One solution to this problem is to change the time-out for a failed service. A second solution is to manually stop the Exchange services before you shut down the server.
Similar to domain controller and global catalog server services, Domain Name System (DNS) services are critical to the availability of your Exchange 2003 organization. On a Windows Server 2003 network, users locate resources by using DNS and Windows Internet Name Service (WINS). The failure of a DNS server can prevent users from locating your messaging system.
To ensure that your Exchange 2003 topology includes reliable access to DNS, consider the following:
Ensure that a secondary DNS server exists on the network. If the primary DNS server fails, this secondary server should be able to direct users to the correct servers.
Integrate Windows Server 2003 DNS zones into Active Directory. In this scenario, each domain controller becomes a potential DNS server.
Configure each client computer with at least two DNS addresses.
Ideally, both DNS servers should be in the same site as the client. If the DNS servers are not in the same site as the client, the primary DNS server should be the server that is in the same site as the client.
Ensure that name resolution and DNS functionality are both operating correctly. For more information, see Microsoft Knowledge Base article 322856, "HOW TO: Configure DNS for Use with Exchange Server."
Before deploying Exchange, ensure that DNS is correctly configured at the hub site and at all branches.
Exchange requires WINS. Although it is possible to run Exchange 2003 without enabling WINS, it is not recommended. There are availability benefits that result from using WINS to resolve NetBIOS names. (For example, in some configurations, using WINS removes the potential risk of duplicate NetBIOS names causing a name resolution failure.) For more information, see Microsoft Knowledge Base article 837391, "Exchange Server 2003 and Exchange 2000 Server require NetBIOS name resolution for full functionality."
For information about deploying DNS and WINS, see "Deploying DNS" and "Deploying WINS" in the Microsoft Windows Server 2003 Deployment Kit.
If your organization has more than one Exchange server, it is recommended that you use Exchange front-end and back-end server architecture. Front-end and back-end architecture provides several client access performance and availability benefits.
Internet clients access their mailboxes through front-end servers. However, in default Exchange 2003 configurations, MAPI clients cannot use front-end servers; instead, these clients access their mailboxes through back-end servers directly.
When front-end servers use HTTP, POP3, and IMAP4, performance is increased because the front-end servers offload some load processing duties from the back-end servers.
If you plan to support MAPI, HTTP, POP3, or IMAP4, you can use Exchange front-end and back-end server architecture to take advantage of the following benefits:
Front-end servers balance processing tasks among servers. For example, front-end servers perform authentication, encryption, and decryption processes. This improves the performance of your Exchange back-end servers.
Your messaging system security is improved. For more information, see "Security Measures" later in this topic.
To incorporate redundancy and load balancing in your messaging system, you can use Network Load Balancing (NLB) on your Exchange front-end servers.
For information about planning an Exchange 2003 front-end and back-end architecture, see "Planning Your Infrastructure" in Planning an Exchange Server 2003 Messaging System.
For information about deploying front-end and back-end servers, see Using Microsoft Exchange 2000 Front-End Servers. Although that document focuses on Exchange 2000, the content is applicable to Exchange 2003.
To build fault tolerance into your messaging system, consider implementing Exchange front-end servers that use NLB. You should also configure redundant virtual servers on your front-end servers.
Network Load Balancing (NLB) is a Windows Server 2003 service that provides load balancing support for IP-based applications and services that require high scalability and performance. When implemented on your Exchange 2003 front-end servers, NLB can address bottlenecks caused by front-end services.
The following figure illustrates a basic front-end and back-end architecture that includes NLB.
Basic front-end and back-end architecture including Network Load Balancing
An NLB cluster dynamically distributes IP traffic to two or more Exchange front-end servers, transparently distributes client requests among the front-end servers, and allows clients to access their mailboxes using a single server namespace.
NLB clusters are computers that, through their numbers, enhance the scalability and performance of the following:
Web servers
Computers running ISA Server (for proxy and firewall servers)
Other applications that receive TCP/IP and User Datagram Protocol (UDP) traffic
NLB cluster nodes usually have identical hardware and software configurations. This helps ensure that your users receive consistent front-end service performance, regardless of the NLB cluster node that provides the service. The nodes in an NLB cluster are all active.
For more information about NLB, see "Designing Network Load Balancing" and "Deploying Network Load Balancing" in the Microsoft Windows Server 2003 Deployment Kit.
With NLB, as the demand increases on your Exchange 2003 front-end servers, you can either scale up or scale out. In general, if your primary goal is to provide faster service to your Exchange users, scaling up (for example, adding additional processors and additional memory) is a good solution. However, if you want to implement some measure of fault tolerance to your front-end services, scaling out (adding additional servers) is the best solution. With NLB, you can scale out to 32 servers if necessary. Scaling out increases fault tolerance because, if you have more servers in your NLB cluster, a server failure affects fewer users.
When configuring your Exchange 2003 messaging system, use Exchange System Manager to create a protocol virtual server for each protocol that you want to support on a specific front-end server.
To maximize availability and performance of your front-end servers, consider the following recommendations when configuring protocol virtual servers:
When configuring NLB for your Exchange 2003 front-end servers, you should make sure that all protocol virtual servers on your NLB front-end servers are configured with identical settings.
If you are not using NLB on your front-end servers, do not create additional protocol virtual servers on each of your front-end servers. (For example, do not create two identical HTTP protocol virtual servers on the same front-end server.) Additional virtual servers can significantly affect performance and should be created only when default virtual servers cannot be configured adequately.
For more information about configuring Exchange protocol virtual servers, see the Exchange Server 2003 Administration Guide.
For information about tuning Exchange 2003 front-end servers, see the Exchange Server 2003 Performance and Scalability Guide.
A reliable storage strategy is paramount to achieving a fault tolerant messaging system. To implement and configure a reliable storage solution, you should be familiar with the following:
Exchange 2003 database technology
Best practices for configuring and maintaining Exchange data
Advanced storage technologies such as RAID and Storage Area Networks (SANs)
For detailed information about planning and implementing a reliable back-end storage solution, see Planning a Reliable Back-End Storage Solution.
By allowing the failover of resources, server clustering provides fault tolerance for your Exchange 2003 organization. Specifically, server clusters that use the Cluster service maintain data integrity and provide failover support and high availability for mission-critical applications and services on your back-end servers, including databases, messaging systems, and file and print services.
The following figure illustrates an example of a four-node cluster where three nodes are active and one is passive.
Example of a four-node 3 active/1 passive cluster
In server clusters, nodes share access to data. Nodes can be either active or passive, and the configuration of each node depends on the operating mode (active or passive) and how you configure failover. A server that is designated to handle failover must be sized to handle the workload of the failed node.
For information about planning Exchange server clusters, see Planning for Exchange Clustering.
Server clustering provides two main benefits in your organization: failover and scalability.
Failover is one of the most significant benefits of server clustering. If one server in a cluster stops functioning, the workload of the failed server fails over to another server in the cluster. Failover ensures continuous availability of applications and data. Windows Clustering technologies help guard against three specific failure types:
Application and service failures. These failures affect application software and essential services.
System and hardware failures. These failures affect hardware components such as CPUs, drives, memory, network adapters, and power supplies.
Site failures in multi-site organizations. These failures can be caused by natural disasters, power outages, or connectivity outages. To protect against this type of failure, you must implement an advanced geoclustering solution. For more information, see "Using Multiple Physical Sites" later in this topic.
By helping to guard against these failure types, server clustering provides the following two benefits for your messaging environment:
High availability The ability to provide end users with dependable access services while reducing unscheduled outages.
High reliability The ability to reduce the frequency of system failure.
Scalability is another benefit of server clustering. Because you can add nodes to your clusters, Windows server clusters are extremely scalable.
Rather than providing fault tolerance at the data level, server clustering provides fault tolerance at the application level. When implementing a server clustering solution, you must also implement solid data protection and recovery solutions to protect against viruses, corruption, and other threats to data. Clustering technologies cannot protect against failures caused by viruses, software corruption, or human error.
Both clustering and fault tolerant hardware protect your system from component failures (such as CPU, memory, fan, or PCI bus failures). Although you can use clustering and fault tolerant hardware together as an end-to-end solution, be aware that the two methods provide high availability in different ways:
Clustering can provide protection from an application or operating system failure. However, a stand-alone (non-clustered) server using fault tolerant hardware (or a server that uses hot-swappable hardware, which allows a device to be added while the server is running) cannot provide protection from these failure types.
Clustering enables you to perform upgrades or installations on one of the cluster nodes, while maintaining full Exchange service availability for users. With stand-alone (non-clustered) servers, you must often stop Exchange services to perform these upgrades or installations. For specific information about how you can maintain Exchange service availability when performing upgrades or installations, see "Taking Exchange Virtual Servers or Exchange Resources Offline" in the Exchange Server 2003 Administration Guide.
Continuous monitoring of your network, applications, data, and hardware is essential for high availability. Software-monitoring tools and techniques enable you to determine the health of your system and identify potential issues before an error occurs.
To maximize availability, you must consistently manage, monitor, and troubleshoot your servers and applications. If a problem occurs, you must be able to react quickly so you can recover data and make it available as soon as possible. To help you monitor your Exchange 2003 organization, you could use the Exchange 2003 Management Pack for Microsoft Operations Manager.
For complete information about Exchange 2003 Management Pack, Microsoft Operations Manager, and other monitoring tools, see Implementing Software Monitoring and Error-Detection Tools.
To increase fault tolerance in your organization, you need to develop and implement a well-planned backup and recovery strategy. If you are prepared, you should be able to recover from most failures.
After considering measures to increase fault tolerance in your Exchange 2003 infrastructure, consider the following additional system-level best practices:
Safeguarding the physical environment of your servers Take precautions to ensure that the physical environment is protected.
Security measures Implement permissions practices, security patching, physical computer security, antivirus protection, and anti-spam solutions.
Message routing Use fault tolerant network hardware and correctly configure your routing groups and connectors.
Use multiple physical sites Protect data from site failures by mirroring data to one or more remote sites or implementing geoclustering to allow failover in the event of a site failure.
Operational procedures Maintain and monitor servers, use standardized procedures, and test your disaster recovery procedures.
Laboratory testing and pilot deployments Before deploying your messaging system in a production environment, test performance and scalability in laboratory and pilot environments.
To maintain the availability of your servers, you should maintain high standards for the environment in which the servers must run. To increase the longevity and reliability of your server hardware, consider the following:
Temperature and humidity Install mission-critical servers in a room established for that purpose—specifically a room in which you can carefully control temperature and humidity. Computers perform best at approximately 70 degrees Fahrenheit (approximately 21 degrees Celsius). In an office setting, temperature is not usually an issue. However, consider the effects of a long holiday weekend in the summer with the air conditioning turned off.
Dust or contaminants Where possible, protect servers and other equipment from dust and contaminants and check for dust periodically. Dust and other contaminants can cause components to short-circuit or overheat, which can cause intermittent failures. Whenever a server's case is open, quickly check to determine whether the unit needs cleaning. If so, check all the other units in the area.
Power supplies As with any disaster-recovery planning, planning for power outages is best done long before you anticipate outages and involves identifying resources that are most critical to the operation of your business. When possible, provide power from at least two circuits to the computer room and divide redundant power supplies between the power sources. Ideally, the circuits should originate from two sources that are external to the building. Be aware of the maximum amount of power a location can provide. It is possible that a location could have so many servers that there is not sufficient power for any additional servers. Consider a backup power supply for use in the event of a power failure in your computer center. It may be necessary to continue providing computer service to other buildings in the area or to areas geographically remote from the computer center. You can use uninterruptible power supply (UPS) units to handle short outages and standby generators to handle longer outages. When reviewing equipment that requires backup power during an outage, include network equipment, such as routers.
Maintenance of cables To prevent physical damage to cables, make sure the cables are neat and orderly, either with a cable management system or tie wraps. Cables should never be loose in a cabinet, where they can be disconnected by mistake. If possible, make sure that all cables are securely attached at both ends. Also, make sure that pull-out, rack-mounted equipment has enough slack in the cables, and that the cables do not bind and are not pinched or scraped. Set up good pathways for redundant sets of cables. If you use multiple sources of power or network communications, try to route the cables into the cabinets from different points. This way, if one cable is severed, the other can continue to function. Do not plug dual power supplies into the same power strip. If possible, use separate power outlets or UPS units (ideally, connected to separate circuits) to avoid a single point of failure.
Security is a critical component to achieving a highly available messaging system. Although there are many security measures to consider, the following are some of the more significant:
Permission practices
Security patches
Physical security
Antivirus protection
Anti-spam solutions
For detailed information about these and other security measures, see the Exchange Server 2003 Security Hardening Guide.
Your routing topology is the basis of your messaging system. As a result, you must plan your routing topology with network, bandwidth, and geographical considerations in mind.
Routing describes how Exchange transfers messages from one server to another. When planning your routing topology, you must understand how messages are transferred within Exchange and then plan a topology for the most efficient transfer of messages. You must also plan the locations of connectors to messaging systems outside your Exchange organization. Careful planning can reduce the volume of network traffic and optimize Exchange and Windows services.
To ensure that your message routing is reliable and available, consider the following high-level recommendations:
Make sure that your physical network has built-in redundancy. For more information, see "Network Hardware" earlier in this topic.
Make sure that you have correctly configured connectors and routing groups. For example, in some scenarios, using Exchange System Manager to configure redundant connector paths can limit a single point of failure.
Configure your connectors to ensure there are multiple paths to all bridgehead servers.
If applicable, make sure that your Simple Mail Transfer Protocol (SMTP) gateway servers are redundant. In large data centers, it is generally recommended that you dedicate specific Exchange 2003 servers to handle only inbound and outbound SMTP traffic. These servers are usually called SMTP gateway servers or SMTP hubs. These servers are responsible for moving SMTP e-mail between clients and Exchange 2003 mailbox servers (back-end servers).
For information about planning your routing design and configuration (including recommendations for creating routing groups and connectors), see Planning an Exchange Server 2003 Messaging System.
For information about how to configure message routing, see the Exchange Server 2003 Transport and Routing Guide.
To improve disaster recovery and increase availability, some organizations use multiple physical sites. Most multi-site designs include a primary site and one or more remote sites that mirror the primary site. The level at which components and data are mirrored between sites depends on the SLA and the business requirements. Another option is to implement geographically dispersed clusters. With geographically dispersed clusters, in the event of a disaster, applications at one site can fail over to another site.
The following sections provide more information about site mirroring and geoclustering.
Site mirroring involves using either synchronous or asynchronous replication to mirror data (for example, Exchange 2003 databases and transaction log data) from the primary site to one or more remote sites.
Using site mirroring to provide data redundancy in multiple physical sites
If a complete site failure occurs at the primary site, the amount of time it takes to bring Exchange services online at the mirrored site depends on the complexity of your Exchange organization, the amount of preconfigured standby hardware you have, and your level of administrative support. For example, an organization may be able to follow a preplanned set of disaster recovery procedures and bring their Exchange messaging system online within 24 hours. Although 24 hours may seem like a lot of downtime, you may be able to recover data close to the point of failure. For information about synchronous and asynchronous replication of Exchange data, see "Exchange Data Replication Technologies" in Overview of Storage Technologies.
A more advanced way to implement fault tolerance at the site level is to implement geographically dispersed clusters. To deploy geographically dispersed clusters with Windows Server 2003, you use virtual LANs (VLANs) to connect SANs over long distances.
Using geographically dispersed clustering to provide application failover between physical sites
Geographically dispersed cluster configurations can be complex, and the clustered servers must use only components supported by Microsoft. You should deploy geographically dispersed clusters only with vendors who provide qualified configurations.
For more information about geographically dispersed cluster solutions with Exchange 2003, see Planning for Exchange Clustering.
For information about Windows Server 2003 and geographically dispersed clusters, see Geographically Dispersed Clusters in Windows Server 2003.
When operating and administering your Exchange 2003 messaging system, it is important that your IT staff use standard IP best practices. This section provides best practices for maximizing the availability of your applications and computers. (This information applies to both clustered and non-clustered environments.)
- Minimize or eliminate support for multiple versions of operating systems, service packs, and out-of-date applications
It is difficult to provide reliable support when multiple combinations of different software and hardware versions are used together in one system (or in systems that interact on the network). Out-of-date software, protocols, and drivers (and associated hardware) are impractical when they do not support new technologies. Set aside resources and time for planning, testing, and installing new operating systems, applications, and hardware. When planning software upgrades, work with users to identify the features they require. Provide training to ease users through software transitions. In your software and support budget, provide funds for upgrading applications and operating systems in the future.
- Isolate unreliable applications
An unreliable application is an application that your business cannot do without, but that does not meet appropriate standards for reliability. If you must work with such an application, there are two basic approaches you can take:
Remove the unreliable applications from the servers that are most critical to your enterprise. If an application is known to be unreliable, take steps to isolate it, and do not run the application on a mission-critical server.
Provide sufficient monitoring, and use automatic restarting options where appropriate. Sufficient monitoring requires taking snapshots of important system performance measurements at regular intervals. You can set up automatic restarting of an application or service by using the Services snap-in. For more information about Windows services, see "Services overview" in Windows Server 2003 Help.
- Use current, standardized hardware
Incompatible hardware can cause performance problems and data loss. Maintain and follow a hardware standard for new systems, spare parts, and replacement parts.
- Plan for future capacity requirements
Capacity planning is critical to the success of highly available systems. To understand how much extra capacity currently exists in the system, study and monitor your system during peak loads.
- Maintain an updated list of operational procedures
When a root system problem is fixed, make sure you remove any outdated procedures from operation and support schedules. For example, when software is replaced or upgraded, certain procedures might become unnecessary or no longer be valid. Pay special attention to procedures that may have become routine. Make sure that all procedures are necessary and not temporary fixes for issues for which the root cause has not been found.
- Perform adequate monitoring practices
If you do not adequately monitor your messaging system, you might not identify problems before they become critical and cause system failures. Without monitoring, an application or server failure could be your only notification of a problem.
- Determine the nature of the problem before reacting
If the operations staff is not trained and directed to analyze problems carefully before reacting, your personnel can spend large amounts of time responding inappropriately to a problem. They also might not be effectively using monitoring tools in the crucial time between the first signs of a problem and an actual failure.
- Treat the root cause of problems instead of treating symptoms
When an unexpected failure occurs or when performing short-term preventive maintenance, symptom treatment is an effective strategy for restoring services. However, symptom treatments that are added to standard operating procedures can become unmanageable. Support personnel can be overwhelmed with symptom treatments and might not be able to correctly react to new failures.
- Avoid stopping and restarting services and servers to end error conditions
Stopping and restarting a server may be necessary at times. However, if this process temporarily fixes a problem but does not address the root cause, it can create additional problems.
Before you deploy any new solution, whether it is fault tolerant or network hardware, a software monitoring tool, or a Windows Clustering solution, you should thoroughly test the solution before deploying it in a production environment. After testing in an isolated lab, test the solution in a pilot deployment in which only a few users are affected, and then make any necessary adjustments to the design. After you are satisfied with the pilot deployment, perform a full-scale deployment in your production environment.
Depending on the number of users in your Exchange organization, you may want to perform your full-scale deployment in stages. After each stage, verify that your system can accommodate the increased processing load from the additional users before deploying the next group of users. For complete information about setting up test and pilot environments, see "Designing a Test Environment" and "Designing a Pilot Project" in the Microsoft Windows Server 2003 Deployment Kit.
To determine how many Exchange servers are required to manage user load, use the following capacity planning tools:

Here’s an interesting question I got the other day:
We are writing code to translate old mainframe business report generation code written in a BASIC-like language to C#. The original language allows “goto” branching from outside of a loop to the interior of a loop, but C# only allows branching the other way, from the interior to the exterior. How can we branch to the inside of a loop in C#?
I can think of a number of ways to do that.
First, don’t do it. Write your translator so that it detects such situations and brings them to the attention of a human who can analyze the meaning of the code and figure out what was meant by the author of this bad programming practice. Branching into the interior of a loop is illegal in C# because doing so would skip all of the code that is necessary to ensure the correct behaviour of the loop. Odds are good that this pattern indicates a bug or at least some bad smelling code that should be looked at by an expert.
Second, this pattern is not legal in C# or VB.NET, but perhaps it is legal in another useful modern language. You could write your translator to translate to some other language instead of C#.
Third, if you want to do this automatically and you need to use C#, the trick is to change how you generate your loops. Remember, loops are nothing more than a more pleasant way to write a “goto”. Suppose your original code looks something like this pseudo-basic fragment:
10 J = 2
20 IF FOO THEN GOTO 50
30 FOR J = 1 TO 10
40 PRINT J
50 PRINT “—“
60 NEXT
70 PRINT “DONE”
The “obvious” way to translate this program fragment into C# doesn’t work:
int J = 2;
if (FOO) goto L50;
for(J = 1 ; J <= 10; J = J + 1)
{
PRINT (J);
L50: PRINT (“—“);
}
PRINT (“Done”);
because there’s a branch into a block. But you can eliminate the block by recognizing that a “for” loop is just a sugar for “goto”. If you translate the loop as:
int J = 2;
if (FOO) goto L50;
J = 1;
L30: if (!(J <= 10)) goto L70;
PRINT (j);
L50: PRINT (“—“);
J = J + 1;
goto L30;
L70: PRINT (“done”);
and now, no problem. There’s no block to branch into, so there’s no problem with the goto. This code is hard to read so you probably want to detect the situation of branching into a loop and only do the “unsugared” loop when you need to.
It is difficult to do a similar process that allows arbitrary branching in a world with try-finally and other advanced control flow structures, but hopefully you do not need to. Old mainframe languages seldom have complex control flow structures like “try-finally”.
> Branching into the interior of a loop is illegal in C# because doing so would skip all of the code that is necessary to ensure the correct behaviour of the loop.
Can you elaborate? Do you mean the loop condition for while-loops, and also the initializer for for-loops (in which case goto silently breaks the semantics of the loop – but this seemingly doesn’t apply to do-while), or some other code that the compiler generates undercover?
It’s more general than loops. In C# it is illegal to branch into the middle of any block from outside the block. With loops, one wants to be able to reason about the invariants of a loop without having to understand how control could have entered the loop. More generally, one should be able to reason about the control flow within a given block solely by looking at that block. You should not have to look at the whole method to understand how a given block in it could be used.
Another way to look at this is to think of the name of the label as being scoped to the block, just like the name of a local declared in the block is scoped to the block. Just as you cannot refer to a local by name outside of its scope, you cannot refer to a label by name outside of its scope.

In a previous life, I had to do just such a beast and wound up doing exactly what you suggested. However I could do some static analysis and only write the IF/GOTO loop if there were a /targeted/ label inside of the original FOR loop. Otherwise, I’d write the more natural corresponding FOR loop.
If I did have to write the IF/GOTO loop I would insert a comment block that indicated what it read originally (FOR) and where the reference to the inner label came from. This facilitated hand-massaging the code later into something more manageable.
Thank goodness there were no COME FROM constructs! 🙂
You can’t do Duff’s Device in C#?! Jeez.
Gotos are fun. I wrote a (lexer) state machine once with no loop. It just bounced around with gotos until it bounced into an endpoint.
It’s weird, but good, that we’ve reached a point when gotos are an exotic construct that you never think about.
Simple suggestion, unroll the part of the loop that is being jumped to, outside of the loop, and insert that part at the jump location … This could get a little complicated if the jump traverses many branches of code, but otherwise I think it could be an option …
When you say this is legal in VB, you mean VB6, right – not VB.Net?
Bizarre. The customer who asked me about this issue said that it worked in VB.Net, but I have just checked the documentation and clearly it does not. Thanks for noticing that. — Eric
So how would you translate this into oh, FORTH, or Python, for example, neither of which has labels.. You need to figure out what the program REALLY needs to do and do it without spaghetti (even flying spaghetti monster) code.
Personally if I was going to manually refactor that code then I’d ditch the GOTOs altogether and just do something like:
IF (FOO) THEN
PRINT "—"
FOR J = 3 TO 10
PRINT J
PRINT "—"
ELSE
FOR J = 1 TO 10
PRINT J
PRINT "—"
ENDIF
PRINT "DONE"
Sure it’s a lot more verbose, but I find it a lot easier to read than the translated block with the looping GOTOs in it.
When people realize today’s if-else are also gotos, there’s gonna be rioting in the streets! 😉
Cleaner would be:
INTEGER JBASE
IF (FOO) THEN
PRINT "—"
JBASE = 3
ELSE
JBASE = 1
END IF
FOR J = JBASE TO 10
PRINT J
PRINT "—"
PRINT "DONE"
Suppose you have something like this:
int i = 0;
if( j < 5 ) goto inside;
for( ; i < 10 ; ++i )
{
do_something( );
inside:
do_more( );
}
Then why can’t you translate it like this?
int i = 0;
if( j < 5 ) do_something( );
for( ++i ; i < 10 ; ++i )
{
do_something( );
inside:
do_more( );
}
This is exactly what Pop Catalin suggested. It will vary on case by case basis, but it is easier to do and more easier to understand.
@Malcolm Fitzsimmons:
Agreed. I would probably pick between that style or my style depending on a few factors, such as how big the actual loop body was, how big the body of the FOO clause was and how often I expected FOO to be true.
Read "Structured Programming with go to Statements". That goto breaks invariant reasoning techniques was established to be wrong.

Yeah, I worked with a guy who really liked that one.
Back in highschool, in my first programing class (Qbasic) our instructor forbade us from using goto’s… if your assignment had one goto in it…. he would trash it… THANK GOD! 8 years later MCAD certified, working for an awesome company… and i would have never gotten this far if I would have been allowed to think that goto was a good thing…
Eliminating goto was supposed to be the panacea for spaghetti code, and yet it continues to plague what could otherwise be fabulous code… Curious…
Guys, goto is not by itself a bad thing in any way. Its evilness is that it is very easy to misuse it, but by itself it is a useful tool in any imperative programming languages. Did you never have to break out of a nested loop? Or a switch nested inside a loop? And if you’re coding in C (not C++), goto is essentially the only robust way to do proper error handling, when you have to check for error (and potentially clean up) after every single function call.
The extreme argument against goto ("Goto is always evil. Always!") is also the argument against break and return, and, to some extent, throw. If you are truly willing to go to these lengths, then you should go all the way, and claim that nothing less than the purity of Haskell is desirable. Which would at least be a consistent position, even though not a very pragmatic one.
But, so long as you stick to an imperative language, some form of goto is necessary and desirable.
By the way you can do a Duff’s device in c#
static void DuffsDevice<T>(T[] from, T[] to)
{
int count = from.Length;
int position = 0;
switch (count % 8)
{
case 0:
to[position] = from[position++];
goto case 7;
case 7:
to[position] = from[position++];
goto case 6;
case 6:
to[position] = from[position++];
goto case 5;
case 5:
to[position] = from[position++];
goto case 4;
case 4:
to[position] = from[position++];
goto case 3;
case 3:
to[position] = from[position++];
goto case 2;
case 2:
to[position] = from[position++];
goto case 1;
case 1:
to[position] = from[position++];
if ((count -= 8) > 0) goto case 0; else break;
}
@pminaev:
An example of combined error-handling in C without using goto:
bool got_error = FALSE;
got_error = do_func_1();
got_error = got_error && do_func_2();
got_error = got_error && do_func_3();
got_error = got_error && do_func_4();
if (got_error) {
// combined error handling
}
Oops, wrong logic (it’s early) but you get the idea.
That’s assuming your functions return bool to indicate error – what about an int error code (note that in that case, && cannot be used, as it will coerce any non-0 "truth" value to 1)?
In practice, most C code I’ve seen uses "if … goto error" and so on. Probably also because it’s far clearer than this trick, too. As I’ve said earlier, sometimes goto is the right way to solve the problem, and working around it only makes things more complicated, all for the sake of "not saying the dreaded word".
We constantly use gotos in all forms except for jumping into a loop or back to the top of a function.
This is our way of drastically reducing the nesting level of if then else/for loops/etc. This point is lost when must younger developers trust the framework to clean up their own objects/allocation and ignore the longer term support cost for a particular block of code.
We’ve been burned with offshore written code that has 15+ levels of nesting in 500+ line functions because the developers refused to use gotos, returns and apparently got paid more for each line of code.
Common code we’ve seen
if (file open is ok)
{
500+ lines of code
}
else
{
do some error handling
}
This would be nested inside of a loop or multiple levels down inside of an if/then else block.
Another example would be multiple nested try/catch statements each to handle a resource allocation/connection failure instead the commonly used block:
if allocate 1 fails goto cleanup_one
if allocate 2 fails goto cleanup_two
if allocate 3 fails goto cleanup_three
body of function (or better a function call to the body to make it easier to see that the allocate and cleanup operations are done in the correct order)
cleanup_three: do cleanup of object 3
cleanup_two: do cleanup of object 2
cleanup_one: do cleanup of object 1
return
@pminaev: int error code can easily be handled in the same way by ANDing got_error with the result of comparing the function to the known good value e.g. if a negativereturn vale indicates error then:
got_error = !got_error && (func1() < 0);
If you dislike the "trick" with the logic short-circuiting then you can use a more explicit version:
bool got_error = FALSE;
got_error = do_func_1();
if (!got_error)
got_error = do_func_2();
if (!got_error)
got_error = (do_func_3() < 0);
if (got_error) {
// combined error handling
}
Either way, the only advantage to the goto approach is that it saves a couple of clock cycles. On most platforms, including most embedded system I’ve worked on, a few clock cycles in neglible.
> Either way, the only advantage to the goto approach is that it saves a couple of clock cycles.
You still miss my point. The advantage of the goto error handling approach is that it is usually more readable than any other workaround. Workarounds for the sake of them are not a good idea.
I always used to think that the GOTO statement was a bad thing, and programming should only use loops and other "prettier" flow techniques.
Over the last few weeks I was playing around writing an MSIL disassembler to look deeper into the code I write… and the first thing I noticed was that compiler translate loops into a seried of GOTO blocks. Typically a for loop would look something equivalent to:
(Initialise looping variable)
goto LABEL1;
LABEL2: (Whatever instructions are inside the block)
(Increment or decrement looping variable as required)
LABEL1: if (Check for loop to be run) goto LABEL 2;
So a trivial loop:
for (int ix = 0; ix < 10; ix++)
{
do_something();
}
do_loop_finished();
gets translated to:
int ix = 0;
goto LABEL1;
LABEL2: do_something();
ix++;
LABEL1: if (ix < 10) goto LABEL 2;
do_loop_finished();
So I am now wondering why we are always told to you loops rather than gotos, when they are just converted back to gotos, thus adding an additional level of translation (and hence sub-optimal code)!
I agree that gotos can be VERY evil…
BUT, they are very useful. I had to write a parser for fiels that could reach up to 20 gigs. Their content was never known until they were read. I came up with a 400 line optimised function, each of the other programmers came up with 700+ line functions.
They had similar flow patterns, except I used goto statements.

@pminaev:
I agree that avoiding "goto" purely out of superstition is a bad idea. But I disagree that a goto version of that code is actually any more readable.
@Russell Anscomb:
Of course. And this is true of most languages. Loops are all just syntactic sugar for various Branch and Jump assembly instructions. Languages themselves are just abstractions of machine code. If you want absolute speed at all cost then why are you using a high-level language at all? You need to write directly in assembler (and you also need to be a genius to outperform most modern compilers).
However the rest of us see the benefit of readable and maintainable high-level code over absolute performance.
It’s probably also worth pointing out that in a modern language, like C#, most error handling will be done by exceptions – which in many ways offer all the same benefits as gotos in this scenario, with the added advantage of carrying information about why they were raised.
Of course ALL flow control becomes "goto" (possibly conditional) at the machine level. Anyone who does not understand that, needs to just hang up their had.
Much more dangerous than "goto" is the infamous "come from" instruction. When
using this, you can cause an arbitrary transfer from any point in the code:
10 x = 1
20 y = 1
30 x = 2
40 Print x,y,z
5000 Come From 20
5001 y = 99
5002 GoBack
(Sorry for posting this 14 days before it’s 35th original publication)
So you cant jump to a goto label within a loop from outside the loop? I didnt know this. But whats that piece of code that Reflector happens to show when decompiling a yield return statemachine?
private bool MoveNext()
{
try
{
switch (this.<>1__state)
{
case 0:
this.<>1__state = -1;
this.<>7__wrap4 = this.<>4__this.GetNodes().GetEnumerator();
this.<>1__state = 1;
while (this.<>7__wrap4.MoveNext())
{
this.<node>5__3 = this.<>7__wrap4.Current;
this.<>4__this.m_alreadyReturnedNodes.Add(this.<node>5__3);
this.<>2__current = this.<node>5__3;
this.<>1__state = 2;
return true;
Label_008C:
this.<>1__state = 1;
}
this.<>m__Finally5();
break;
case 2:
goto Label_008C;
}
return false;
}
fault
{
this.System.IDisposable.Dispose();
}
}
Is it just Reflector making up a while statement while the original il statements just are gotos?

The discussion is moving a litle away from the first remark about automated migrated code.
Yes excessive and wrong use of Goto is very bad. But looking manual at 10.000.000 lines to remove them is a huge task. Analyzing and refactoring code solves a number of them but still not all.
The IL itself does allow it so why not the compiler. Let the programmer be the judge to use it or not.
In vb.net indead the goto into a for is not allowed but a goto into an if is. And possible other code levels?
Dim j As Integer
j = 1
GoTo l50 ‘ <—- allowed
If (1 = 1) Then
j = 2
l50:
j = 3
End If
GoTo l60 ‘<———– not allowed
For j = 1 To 5
l60:
I’m suprised that people can be so ‘religious’ in their renouncing of gotos. I thought kind of singlemindedness was a Java guy’s thing.
Yes, most of the time the higher level control flows are better, but there are exeptions.
Take the example of a controlflow schema from Visio. When you want to implement that with functions, you have a problem because after the call ends, you end up where you called the function. That’s not what you want, you wanted to go to another Process or Decision. (note the use of the words ‘go’ and ‘to’ 😉 In those cases program with Gotos is much more readable than trying to do that with functions.
Also, every function call is a push to the stack, they are not cheap. If you need really fast execution of your code, gotos can actually help you squeeze out that last bit of speed, although this can be at the expense of readabiliy, i’ll agree there.

> The IL itself does allow it so why not the compiler. Let the programmer be the judge to use it or not.
Because the compiler must enforce a semantic level of meaning on the code so that it can effectively generate IL code that does what you wrote in the higher level language.
Consider the difference between for loops and if-else statements. There is quite a bit of difference in the amount of setup required to make each work.
if-else: No setup required, beyond performing the test condition and branching to the else part. Since there’s no setup, it’s no problem to goto into either the if-body or else-body.
for loop: At minimum, initializing the loop index and check that it meets the test condition. (foreach is even worse… find the appropriate enumerator, get that all setup, etc., etc…) With all this setup, how do you reasonably do a goto into the body of a for loop AND get provably correct code for EVERY case? Not too likely. (On the other hand, you can goto out of a for loop, because that amounts to little more than a break.)
I meant flowchart from Visio to be precise.
Nothing like stepping on a setjmp / longjump landmine. I’ve seen some pretty clever exception-like handling built around this construct using C/C++. It drove me nuts till I figured it out. Another developer had called setjmp from main, then whenever his deep library code encountered an error he’d call longjump. The longjump would set the instruction pointer back to the beginning of the program.
What would people say at goto’s funeral?
goto’s wife: "Oh my sweet goto, I can’t loop without you"
goto’s kids: "we want our goto back"
goto’s 3rd cousins’ brother in-laws’ 5th pets’ owner: "He was pure evil, evil I tell you!"
I would suggest converting the code to MSIL, then decompiling the MSIL into C#. That way you get C# code, but it will still have loops where ever possible.
This code
10 J = 2
20 IF FOO THEN GOTO 50
30 FOR J = 1 TO 10
40 PRINT J
50 PRINT "—"
60 NEXT
70 PRINT "DONE"
can write on C# using new bool variable:
j = 2;
bool foo1 = foo;
if (!foo)
j = 1;
for (; j <= 10; j ++)
{
if (!foo1)
print (j);
foo1 = false;
print ("—");
}
print ("DONE");
Any code do not repeates twice!
You can use foo instead foo1, when this variable do not required in other code part.
I don’t think anyone here fails to realize that all flow-of-control structures end up as GOTO’s at a machine level. The point is that the machine can manage the GOTO’s, but for humans its like reading a story, telling someone to jump two pages ahead, then jump three pages back. Yeah, you can do it, but geez, does that make it a good idea? Heavens – the computer can count to a zillion in binary, but that doesn’t mean its a good idea for human consumption.
That aside, my personal beef isn’t with "goto’s" per se, but when they are being used in obviously lazy situations when just a few minutes’ effort would have created a more streamlined control flow structure. In *most* cases, a GOTO is a hack, an amputation of logic where a few stitches of design and discretion would have avoided an ugly and usually unnecessary scar. I’ve rarely seen a structure made *more* elegant with a blunt GOTO. But that’s just me…
GOTO is all about sequence in the context of state. Code in this form is inimical to parallelisation.
This is easy to automate with functional programming languages, where dependencies on evaluation sequence are necessarily explicit. It is damn near impossible to automate in procedural languages where many dependencies are not only implicit but often indirectly implicit (due to side effects).
When a language requires explicit declaration of dependencies, laziness inhibits their spurious creation. Better quality code results, and it is incidentally more amenable to optimisation for multiple CPUs.
As in life, time is the great enemy.
I think people are confusing GOTO with branching.
GOTO is a programming statement which allows unstructured branching. Other programming statements (if-then, for, while, throw) only allow branching within a particular context or programming structure. Unstructured branching allows you to write incomprehensible code *very* easily. For example (using pseudo-basic)
10 x = 110
20 if ( x is even ) goto 40
30 x = 3 * x + 1
40 x = x / 2
50 if ( x > 10 ) goto 20
60 print x
I mean, never mind what x might be at the end, can we even be sure this will finish for different start values of x?
(Please don’t get caught up on this being a mathematical example, BTW. Statements 20 to 50 could be totally non maths related – as long as they interfere with each other you are going to get a problem).
It’s very easy with unstructured branching to start getting this sort of effect. Of course, you could use GOTO to duplicate structured branching (like duplicating a while loop), but why do it? It is far nicer when you come to look at your code to know there are *no* GOTOs in it rather than have to analyse whether each individual GOTO is sensible or not.
As to the oft quoted example of error handling in a sequence of method calls, I believe this indicates bad design. First of all I think you need to carefully consider what *is* an error, then isolate your error handling in one group of methods or classes or whatever, so that the rest of your code isn’t burdened with constantly having to check whether things are happening ok. i.e., it is better to write:
method_a()
{
method_a_1();
method_a_2();
etc
}
– than:
method_a()
{
if ( method_a_1() == ok )
{
if ( method_a_2() == ok )
{
etc
}}}}}}}}}}}}}}}.
– or some equivalent using gotos.
Where you simply are unable to pre-check for an error (like that nuclear refinery you were monitoring has just gone off-line), you should probably use an excepion and exit (gracefully) until somebody fixes the problem.

for(J = FOO ? 3 : 1; J <= 10; J++)
PRINT (string.Format("{0}rn—",J));
PRINT ("Done");
What I was trying to say is that the code should be refactored properly. Using Goto is ugly and difficult to read. Simply check what the code is trying to achieve and find the best way to replicate that functionality.
Which you will note was my first suggestion, yes. But what if you have five hundred thousand lines of goto-ridden mainframe code to translate? “Ugly and difficult to read” is better than “not working”, and cheaper and more accurate than “translate five hundred thousand lines of code by hand”. — Eric
Just because the original code uses a Goto, that doesn’t mean our new code has to use any at all. We could similarly do this:
int j = FOO ? 3 : 1;
while (j<=10)
PRINT (string.Format(“{0}rn—“,J++));
PRINT (“Done”);
Using your human intelligence to create a goto-free program that matches the semantics of one particular code fragment is easy. Writing a program that does that to any arbitrary fragment is rather more difficult, I assure you. — Eric
(with a lower case j in line 3, obviously)
Your point about the difficulty in understanding convoluted code is well taken. In fact some of the coded solutions produced wrong results. In the case where FOO is true they fail to start and end the list with "—".
Actually, your example and solution point out the fundamental translation problem and solution. Antique BASIC treated for a FOR loop index as a global variable and the loop condition was checked in the NEXT statement (Always on iteration was executed). The best way to handle the translation problem is to break the FOR loops into initialization, Value adjustment, and conditional jumps, much like you did ( I would check end conditions at the NEXT statement ).
There are also wonderful dialect specific factors like what is the value of j after the loop? Is it 10 or 11? That would depend on the specific implementation and is unfortunately something that may matter for the code that followed. After all it was often possible to jump out of FOR loops before termination.
if (StatusOK) {
if (DataAvailable) {
ImportantVariable = x;
goto MID_LOOP;
}
} else {
ImportantVariable = GetSomeValue();
MID_LOOP:
//Lots of code
}
I’m disappointed that no-one has mentioned Steve McConnell yet.
Eric:
If you have 500,000 lines of working code which is riddled with GOTO statements, and you then replicate it on a line-by-line (or fragment-by-fragment if you prefer) basis, there’s no guarantee that it’s going to work in the target environment. There are other factors such as that pointed out by bmann: The value of J upon exit may be different, which means the code could fail catastrophically at its first run, or even at some later point when FOO eventually does equal True, and then you’d be left with the serious headache of having to debug it. If you untangled it properly, it would make that debugging much more simple and the code would be readable to anyone else who came to look at it.
Aside from that, if it’s working, why would you move it to another language?
bmann: Good point… but with our new refactored code we should be able to see exactly where the problem is and what the problem is at aa glance 🙂
Seriously, we have methods now…… If you need to jump to something inside a loop, then it should probably be in a separate method.
With regard to Duff’s device (see comments from A.C.Hynes and Matthew Whited above) here is another C# version which is closer to the original. C# is surprisingly expressive at times:
namespace DuffsDevice
{
using System;
class Program
{
static void Main(string[] args)
{
unsafe
{
short[] data = new short[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
short register = -1;
fixed (short* dataPtr = &data[0])
{
DuffsDevice(®ister, dataPtr, data.Length);
}
Console.WriteLine(register);
}
}
/// <summary>
/// C# approximation to Duff’s device.
///
///);
/// }
/// }
/// </summary>
/// <param name="to"></param>
/// <param name="from"></param>
unsafe static void DuffsDevice(short* to, short* from, int count)
{
int n = (count + 7) / 8;
switch (count % 8)
{
case 0:
*to = *from++;
goto case 7;
case 7:
*to = *from++;
goto case 6;
case 6:
*to = *from++;
goto case 5;
case 5:
*to = *from++;
goto case 4;
case 4:
*to = *from++;
goto case 3;
case 3:
*to = *from++;
goto case 2;
case 2:
*to = *from++;
goto case 1;
case 1:
*to = *from++;
if (–n > 0) goto case 0; else break;
}
}
}
}
re: Duff’s Device… Hand-rolled optimization in C#? You guys are funny.
Turns out that a simple loop to iterate through a safe array can be a bit faster than my version of Duff’s Device in .NET. A loop to iterate through allocated stack space (using stackalloc) using an unsafe pointer is much faster. So, ‘Duff’s device’ in C# is sub-optimal. A case of hand-rolled de-optimization! Full marks to C# for being so expressive, but don’t use the technique!
this is funny stuff.
We are being guided to the old, frustrating, spider webs of looping with GOTOs.
this shouldnt practically be an approach in professional development using C#.
One time long ago I inherited a program written in C-tran. The author knew and thought in FORTRAN but had to code the app in C, and a veritable mess of code resulted that contained over 400 GO TO stetements. We stumbled along maintiaing it, never given the time to rewrite what was "working" but always allowed the time to analyze the mess of spaghetti for unintended consequences of the changes we were planning to make (and deal with the ones we did not foresee).
We recruited a bright guy from the customer support team to come into the product development team and his soel condition for accepting the position was they he be allowed to rewrite that app. It was accepted and the final product after3 months was easier to understand, easier to maintain and easier to extend.
GOTO is just a tool – but it is VERY dangerous in the hands of those who do not fear it.
Bad code is bad code. One needs to understand what branching into a FOR statement in their compiler means. I have used languages where there is only the goto. I have also see bad FOR statements.
10 FOR i = 1 TO 10
20 PRINT i
30 NEXT i
40 LET i = i * 2
50 PRINT i
What is the value of i? 20 or 22. This depends on the BASIC version.
Of course we should not use i outside to loop.
Reading most of this thread, I was amazed to discover how interesting it is to look at GOTO from 20 or 30 different points of view.
Getting back to the question that started this thread: the reason she/he wants to convert the old BASIC code to C# is (presumably) so that it will use the .NET CLR and interoperate with other .NET code. The problem is a kind of "impedance mismatch" meaning that BASIC is so dumb, and C# is so smart, that conversion is impractical. What we need is a cruder version of C# (call it "C-dumb") that is closer to the BASIC code. Has anyone considered FORTRAN?
Seriously, I once had to write a state machine once to handle Asterisk telephone events and it was a heck of a lot easier to write, read and modify using a few GOTOs versus keeping it "pure" with strange WHILEs.
The argument that MSIL uses GOTO so we should use them too is suspect. Consider writing a specification for a steel screw. Yes, it is made of molecules but when you order a certain screw do you really want to describe how all the molecules relate to one another? It is the wrong level of abstraction.
Maybe God Almighty will write the answer with fiery letters in the sky: "GOTO IS/IS NOT HARMFUL!"
How much knowlege is available about how the original program works, or (more importantly) what it is supposed to be doing?
A lot of old code can be reduced (in lines of codes) by 20 to 80%, purely on the basis that much of it was cut/pasted from other code that did the same thing on a different instance of data. This is why classes/objects/interfaces/etc came about to begin with.
I agree it is painful to take in hand thousands of lines of code and re-design and re-write it, but it many cases it is well worth it, and would take a lot less time than one might think (there is a certain moment of inertia that begins to build once you get familiar with a coding style no matter how ugly it might seem).
For the love of god!!
Why would you do a direct translation of the code? Just use a loop and some if conditions in it to skip sections.
DO NOT USE GOTO!
Why? Well, suppose you have a million lines of code to translate. Your choices are (1) spend 10 hours writing a literal translator that generates ugly code, (2) spend 10 hours writing a literal translator and then 90 hours rewriting all the code that involves gotos, or (3) spend 10000 hours rewriting the whole system from scratch. The costs of those three choices are $1000, $10000 and $1000000, respectively. Suppose you have to pay for it. Which would you choose? How much are you willing to spend on beautifying code that already works just fine? — Eric | https://blogs.msdn.microsoft.com/ericlippert/2009/03/10/loops-are-gotos/ | CC-MAIN-2016-36 | en | refinedweb |

InvalidMidiDataExceptionindicates that inappropriate MIDI data was encountered. This often means that the data is invalid in and of itself, from the perspective of the MIDI specification. An example would be an undefined status byte. However, the exception might simply mean that the data was invalid in the context it was used, or that the object to which the data was given was unable to parse or use it.

This article provides a drag and drop way of creating radio button GridView row selectors that behave in the same way as the GridView's own "Select" link buttons.
GridView
One thing that's always bothered me about the GridView control is the counter-intuitive appearance of the Select link provided to select a single row. Since pretty much every other time you ask your user to select one item in a list you do it with radio buttons, I couldn't help but feel it would have been more intuitive to make the Select button a radio button. As it happens, this was one of the first things I thought when I started learning ASP.NET two years ago. But now, it didn’t exactly prove trivial to implement. I found some articles telling me how to do it, but these involved a bit of wiring per control and, really, if you're going to apply radio button row selection across your entire site, it should be much simpler than that just from a maintainability point of view.
Now that I've had more experience and studied for a few qualifications, I came up against the same issue again, and decided to solve it properly so I wouldn't have to worry about it anymore. I wanted a pure drag and drop control with no wiring, to replace the Select link, and this is what I came up with.
Since it's a pretty simple piece of code all in all, you can see the control in all its glory below:
[DefaultProperty("Text")]
[ToolboxData("<{0}:GridViewRowSelector</{0}:GridViewRowSelector>")]
public class GridViewRowSelector : RadioButton
{
protected override void Render(HtmlTextWriter writer)
{
GridViewRow row = (GridViewRow)this.NamingContainer;
int currentIndex = row.RowIndex;
GridView grid = (GridView)row.NamingContainer;
this.Checked = (grid.SelectedIndex == currentIndex);
this.Attributes.Add("onClick", "javascript:" +
Page.ClientScript.GetPostBackEventReference(grid,
"Select$" + currentIndex.ToString(), true));
base.Render(writer);
}
}
Using the code is simple, just follow these steps:
Then, just drag and drop the GridViewRowSelector from your toolbox into a template field on the GridView control.
GridViewRowSelector
To create the template field on the GridView, select the Common Functions menu for your GridView (the little arrow at the top right corner in Design view), select Add Column, and then add a TemplateColumn with no header text.
To get the designer up that allows you to drag an element into the template field, select the Common Functions menu again for your GridView, then select “Edit Templates”. You should be able to select the ItemTemplate for your template column and drag the GridViewRowSelector into the appropriate box on the designer. Do not worry that it displays an error – this is simply because I haven’t yet added an appropriate control designer that deals with the design mode. I may do this later, but feel it’s not necessary since the control displays correctly at design time outside of template editing.
If you set the GridView's SelectedRow
Of course, you can’t just fire the same JavaScript command to impersonate a postback from the Select link as ASP.NET provides measures against this for security reasons (such as preventing XSS attacks), so you need to register the postback link.
The simple bit was keeping radio button display in line with that of the selected row. The server control itself is just an extended radio button that updates its own Checked. | http://www.codeproject.com/Articles/22823/Simple-GridView-Radio-Button-Row-Selector | CC-MAIN-2016-36 | en | refinedweb |

->
Accepted.
->
Accepted.
No regrets given
<alexmilowski>
Alex: Essentially, we want to get
it right without describing a particular algorithm
... I took the text from the XML spec and tweaked it a bit
... The algorithm in the proposed Appendix G is based on Henry's proposal.
Norm: I'm happy with the changes to section 5, I'll need to study the appendix more
Alex: The appendix is non-normative, right?
Norm: Yes.
<ht> HST agrees
Richard: About the retreival
URIs, if you did it naively, you might think that you had to go
and fetch the document every time to see if its retreival URI
winds up being the same as one you've already got.
... But in practice, if its literal URI is the same, you can assume its actual URI is the same too.
Alex: Do we have language elsewhere about consistency of resource?
Richard: Even if it did change, there's no gaurantee that you'll see it.
Norm: So we should say that in section 5
Richard: Either that, or some generral statement along the lines that Alex suggested
Norm: I think a general statement is probably the way to go
<MoZ> I think we cannot avoid caching neither
Alex: Maybe we could do a special case for import. Shouldn't we say that however you get a URI, the declarations will be consistent.
<scribe> ACTION: Alex to tweak the text of of p:import [recorded in]
Norm: I thought we were clear on 95, but yes we should be
<scribe> ACTION: Norm to check the clarity of the spec [recorded in]
Norm: Static error 27.
Richard: Namespaces don't appear in the attributes property in the infoset
Alex: I think we should allow
users to set xmlns: attributes.
... Namespace fixup will correct user errors.
Richard: I don't think so.
... Namespaces aren't attributes as far as the infoset is concerned.
Alex: I think p:add-attribute could add namespaces.
Richard: Bad. Bad. Bad.
Henry: Here's the question: can you use xsl:attribute to add a namespace decl?
Norm: No.
Henry: Right, then add-attribute shouldn't either.
Alex: But you could still do it with a transform
Henry: I think my analysis holds
Norm: +1
Richard: The rule should be that you can't manipulate namespaces by manipulating namespace attributes
Henry: The only circumstance you need it for is when you want to create a prefix for a QName that you're going to use in a value
Alex: I think add-attribute needs a modification and set-attributes needs a clarification.
<scribe> ACTION: Alex to consider the attribute steps and make appropriate changes [recorded in]
Richard: In a sense this is already implicit in the infoset conformance section.
Mohamed: I'm not sure I understand the path. The original question was do the namespace attributes get copied. The answer is 'no'
Alex: Right. We're going to clarify that set-attributes doesn't copy them and clean up the other steps too.
Norm: Yep
Alex: Event/consequence ordering is determined by the connections.
Norm: What I recall is that if
you mandated document order, then you'd have to make forward
reference an error. But the impl can fix the order, so why make
theuser move teh steps around?
... It seems an unnecessary burden on the user.
Henry: I still don't know what he means by "do things"
Some discussion of what ordering actually means
<MoZ> it is NOT a total order at all !
<MoZ> 1- parallele exection need this feature
<MoZ> 2 - automatic generation would also need this
Richard: I think there are
straightforward cases where it's natural to write in the
pipeline using forward references.
... Consider a straightforward pipeline with an XSLT step in the middle where the stylesheet is generated. It's natural to put the stylesheet generation at the end of the pipeline.
... Is it always possible to write pipelines without forward references?
Norm: I think so.
Richard: Another way to say this is that the XML syntax is just one representation of the pipelien. It could also be represented with a box-and-arrow diagram.
Alex: We're all in agreement,
right?
... Maybe a note?
<scribe> ACTION: Henry to reply and close the issue [recorded in]
Alex: We have comments that
continue to straggle in.
... What is our plan?
Norm: We're going to do another
last call, as soon as that's ready we'll push it out
... Until then, I don't see any harm in looking at the comments that come in.
Adjourned.

This paper uses FloppyTail but is not related to development.
This code was written for a relatively singular application. The system in question was a protein with a long (dozens of residues) flexible tail, which was not seen in crystal structures. Biochemical evidence suggested a particular binding site for the tail on a known binding partner (the two binding partners also had a known binding interface separate from this tail). The code was intended to model the reach of the long flexible tail and determine whether the hypothesized binding site was plausible.
The protocol is more useful for testing hypotheses about possible conformations, and exploring accessible conformation space, than for finding "the one true binding mode". If your tail is truly that flexible it might not have a "one true binding mode."
The algorithm is fairly simple: small/shear/fragment moves in centroid mode to collapse the tail into some sort of folded conformation from an initially straight-out-into-space extended conformation, and small/shear moves with repacking to refine its position. This is conceptually similar to how abinitio folding works, although it is not refined for that purpose (and does not contain temperature scheduling, etc).
The code is compatible with constraints during the centroid phase (passed in via commandline). Early modeling proceeded using constraints and some small hacks to help guide models to the hypothesized tail-binding site. Ultimately this was not necessary for the original system, but the code retains the ability to use constraints, etc. Your mileage may vary. UPDATE: The code is compatible with constraints in both phases.
This code is NOT intended to do "half-abinitio" where you know half a structure and want to fold the other half. Although it is modeled on abinitio, it is only tested on a truly floppy tail, and I have no idea if it is able to fold compact structures. It is resolutely not supported for that purpose.
See test/integration/tests/FloppyTail/ for example usage. Basically all you need is an input structure.
This code was intended for a single purpose, but it may work if you have a similarly flexible tail. It can also model internal flexible regions between domains.
FloppyTail supports three types of options: general rosetta options (packing, etc.), generic protocol options like "how many cycles" borrowed from the (unreleased) AnchoredDesign application, and FloppyTail specific options.
FloppyTail options
AnchoredDesign options (borrowed for simplicity, not tied to AnchoredDesign in any other way); all are in the AnchoredDesign namespace
General options: All packing namespace options loaded by the PackerTask are respected. jd2 namespace options are respected. Anything very low-level, like the database paths, is respected.
For release 3.4, FloppyTail supports multiple flexible linkers. To use these, you have to write your own MoveMap file to tell FloppyTail what is flexible, and pass it in via the flag in:file:movemap. The formatting is described in the header to the function core::kinematics::MoveMap::init_from_file (probably at core/kinematics/MoveMap.hh). Briefly, do this:
20 30 BBCHI 54 67 BBCHI
to define flexible regions running from residues 20 to 30 and 54 to 67. This is in internal Rosetta residue numbering (from 1), not PDB numbering.
To use this feature you must also NOT use the following flags, because the movemap handles these data, so the program is set up to ignore inputs from these flags if passing a movemap.
You'll be using this application to model mostly unstructured regions. You should not put a lot of stock in any individual model. This is not the sort of application where you'll run it 10 times and then take the best-scoring result as an accurate guess for the actual protein structure.
In general you should pick some metric predicted by the model (if you read the paper, you'll see that it was a distance between two residues later found to be chemically crosslinkable). You can then mine the model population to see what this metric looks like in the top-scoring fraction of models. The extra_analysis functionality will facilitate this. I suggest histograms.
For 3.2, there was a major under-the-hood change which decreases runtime, scaling favorably for very long tails. For the publication case it decreases runtime 10-25%.
For 3.3, the publication flag was added for simplicity. The C_root flag was added to speed computation on non-c-terminal tails. Constraints work in fullatom mode. Full support for domain assembly (internal linkers) was added.
For 3.4, I added the ability to specify a custom MoveMap, which also allows for multiple rigid and flexible regions. | https://www.rosettacommons.org/manuals/archive/rosetta3.4_user_guide/d8/d39/_floppy_tail.html | CC-MAIN-2016-36 | en | refinedweb |
It is 6 AM. I am awake summarizing the sequence of events leading to my way-too-early wake up call. As those stories start, my phone alarm went off. Sleepy and grumpy me checked the phone to see whether I was really crazy enough to set the wake-up alarm at 5AM. No, it was our monitoring system indicating that one of.

then you will face.
Interesting thing, thanks for sharing.

This weekend the most expected version of HMC was released for service providers to deploy it. With this version, service providers can offer OCS (IM, Collaboration, PC-toPC VoIP) services as part of their online services. At the same time support to Windows 2008 and WSS 3.0 SP1 is included in this solution.
You can have access to the bits of the solution from the following location:
Or for those who are interested in developing on top of MPS (i.e. self-service portal, namespaces, increase the business logic of the current APIs, etc.) there is a SDK available as well for developers to consume:
The documentation to migrate from previous versions is still pending, but it will be released soon. If you have HMC 4.0, you shouldn't expect too much of impact in your APIs or portals already implemented. If what you have is HMC 3.5 or earlier, you should consider a similar migration path like to HMC 4.0 with the addition of migrating LCS to OCS 2007. Don't forget to consider these migrations paths while deploying the solution. | http://blogs.technet.com/b/alexmga/archive/2008/06/16/hmc-4-5-is-available-now-deploy-deploy-deploy.aspx | CC-MAIN-2014-15 | en | refinedweb |

Hi all,
A design question is with us tonight, I would like to have your opinion.
Imagine a class Vector2,Vector3,Vector4, all of them has a global function to compute the dot product :
VectorN VectorDot( const VectorN& A, const VectorN& B ); N is 2, 3 and 4.
What is the best design, Make it global in the namespace or static for each class ?
First option : Namespace::VectorDot( a, b ); Second option : Namespace::Vector2::Dot( a, b );
Same for math function (abs,clamp,sqrt...), global or static in a Math class ?
I was a big user of global function and I have changed to static into a class recently, it's just a design question but it's nice to have differents opinion with experience of each.I have changed because the class can be seen like a scope.

The visit framework is extensible via a plugin mechanism. Plugins objects can provide methods, which are called on every request. The plug-in mechanism can be useful for answering questions like ‘How long does a user browse my site?’, ‘What browsers do my users use?’, or ‘How effective is this page in generating a specific response?’. These questions might be difficult to answer using regular TurboGears controllers, but are greatly simplified using Visit.
The tubogears.visit module has an enable_visit_plugin method that you can call to register an object with Visit. Your object only needs to implement one method, record_request.
So, a very simple visit plugin could be implemented in as little as something like:
simplevisit.py:
import turbogears import logging log = logging.getLogger('myapp.simplevisit') class SimpleVisitPlugin(object): def record_request(self, visit): log.info("Visit key: %s" % visit.key) def add_simple_visit_plugin(): log.info("Registering the SimpleVisitPlugin") turbogears.visit.enable_visit_plugin(SimpleVisitPlugin()) turbogears.startup.call_on_startup.append(add_simple_visit_plugin)
If you import this simplevisit.py module into your main controller.py, you should see information about the visit key show up in your log output.
In the example above, record_request takes an argument visit. This visit object is not the same Visit as is in the default model.py, but rather a very simple object defined in turbogears.visit.api. It has only two properties:
This object is also assigned to cherrypy.request.tg_visit, and so it can be accessed inside of any regular controller.
Now that we have a start on what all the pieces are, we can flesh out a slightly more involved example. Say we have a requirement that we want to know what browsers our visitors are using. Ok, we could parse the log files right now for that information and get a pretty reasonable estimate. But, since we are talking about our Visit hammer, this problem is looking an awful lot like a nail.
First let’s extend our model.Visit class just a bit by adding a browser column:
class Visit(SQLObject): class sqlmeta: table = "visit" visit_key = StringCol(length=40, alternateID=True, alternateMethodName="by_visit_key") created = DateTimeCol(default=datetime.now) expiry = DateTimeCol() browser = StringCol(length=80, default=None) # new # rest of Visit continues ...
Update your database with the new browser column. Next, add the following file to our project.
browservisit.py:
import turbogears import cherrypy import logging log = logging.getLogger('myapp.browservisit') from model import Visit class BrowserVisitPlugin(object): def record_request(self, visit): if visit.is_new: # fetch the the user-agent string the browser gave to cherrypy ua = cherrypy.request.headers.get('User-Agent', None) # The UserAgent class reduces the user-agent into a very coarse # list of types, Firefox, Safari, IE. # If you need more fine-grained information you will need to # write your own class to do it, or just comment the next line # out and store the raw user-agent string ua = turbogears.view.UserAgent(ua) # Find the appropriate model.Visit object mvisit = Visit.by_visit_key(visit.key) # store the browser in the database log.debug('Setting model.Visit.browser=%s' % ua.browser) mvisit.browser = ua.browser def add_browser_visit_plugin(): log.info("Registering the BrowserVisitPlugin") turbogears.visit.enable_visit_plugin(BrowserVisitPlugin()) turbogears.startup.call_on_startup.append(add_browser_visit_plugin)
Import the browservisit.py module into controllers.py, and browser information should now be stored in each model.Visit object.
Note above that we are using the is_new property to so that we only set the user agent information on the visitor’s first request. This check prevents a lot of redundant processing on the Visit object (fetching it and saving it back to the database), and should be incorporated any time you have an item that won’t change over the life of the visit.
Another usage example would be adding the ability to track IP addresses for each new visit. Assuming you already have enabled visit tracking, here are the steps to create a visit plugin that does just that.
Add the following in your app’s model.py:
class VisitIP(SQLObject): class sqlmeta: # SQL object default naming is visitor_i_p, not pretty table = 'visit_ip' visit = ForeignKey('TG_Visit') ip_address = StringCol(length=20)
Create the table in your database with tg-admin sql create --class=VisitIP.
Make a new module in your project named visit_plugin.py. Its contents are as follows:
import logging from turbogears import config, util, visit from model import VisitIP log = logging.getLogger('turbogears.visit') def ip_tracking_is_on(): """"Return True if IP tracking is properly enabled, False otherwise.""" return config.get('visit.on', False) and config.get('visit.ip_tracking.on', False) # Interface for the TurboGears extension def start_extension(): if not ip_tracking_is_on(): return log("Visit IP tracker starting.") # Register the plugin with the Visit Tracking framework visit.enable_visit_plugin(IPVisitPlugin()) def shutdown_extension(): if not ip_tracking_is_on(): return log("Visit IP tracker shutting down.") class IPVisitPlugin(object): def __init__(self): log("IPVisitPlugin extension loaded.") visit_class_path = config.get("visit.saprovider.model", "turbogears.visit.savisit.TG_Visit") self.visit_class = util.load_class(visit_class_path) def record_request(self, visit): # This method gets called on every single visit # we only want to record the IP if this is a new visitor if visit.is_new: # retrieve the actual Visit object v = self.visit_class.lookup_visit(visit.key) # add a new visit ip object to the database VisitIP(visit=v, ip_address=cherrypy.request.remoteAddr) # if you are using a SQLAlchemy model you might want to add # session.flush() def new_visit(self, visit_id): # This method gets called the first time the visit is started. # I think IP tracking makes sense in here.
The start_extension and shutdown_extension functions are called by turbogears when starting up and shutting down. The key in this process is the visit.enable_visit_plugin call, which registers your plugin with the visit framework.
In your project’s setup.py, add an entry_points parameter to the setup() function:
setup( # [...] lots of stuff snipped test_suite = 'nose.collector', # begin new entry_points=""" [turbogears.extensions] my_visit_extension = ip_plugin.visit_plugin """, # end new )
My project’s package name is ip_plugin, you will need to adapt this to your project so that the entry point references the right module in your project.
Add a configuration setting so that the tracking can be turned on and off. Somewhere in your app’s deployment configuration file add the line
visit.ip_tracking.on = True
This step just re-generates the egg information for your project so that the extension actually gets called at runtime. From the command line, at the root level of your project run
python setup.py egg_info
That’s it. Fire up your project and you should be tracking ip activity just like the NSA.
It is also be possible to register the plugin simply by adding a call of visit.enable_visit_plugin() to the turbogears.startup.call_on_startup list somewhere in your app’s controller code as in example 1 above, but the solution in this example allows to keep your visit plugin in a completely separate package and enable it in your application’s setup.py without touching the code of your application (provided its Visit model is compatible).
Suppose that we have a website where we are selling a service (e.g. something like Vonage or Netflix). We have a bunch of pages giving information about our service, and a sign-up process where people buy the service. What we want to know is “How many people visiting our site actually buy our service?” In other words, how effective is our website in converting visitors to clients?
Fortunately, this is something that is relatively easy to to accomplish using Visit. First, let’s create a special model class for this specific project.
model.py:
class VisitSaleMonitor(SQLObject): visit_key = StringCol(length=40, alternateID=True, alternateMethodName="by_visit_key") pitch_time = DateTimeCol(default=None) sale_time = DateTimeCol(default=None)
Nothing too spectacular is going on there; we are just creating a place-holder to store when the visitor hit the areas of the site we are interested in. Go ahead and add the new table to your database:
tg-admin sql create --class=VisitSaleMonitor
Now, we are going to build our Visit plug-in. There really isn’t too much to this, just some simple logic to log what our visitors do. Assume that our ‘pitch’ begins with the main page (i.e. /index or /) and the sales process ends with the /sale_complete controller.
salemonitor.py:
import logging from datetime import datetime import turbogears from cherrypy import request from turbogears import identity from sqlobject import SQLObjectNotFound from model import VisitSaleMonitor log = logging.getLogger('myapp.salemonitor') class SaleVisitPlugin(object): def record_request(self, visit): path = request.object_path # ignore requests for things in /static if path.startswith('/static/'): return # If we wanted to ignore registered users from our analysis, # we might do something like the following: # if not identity.current.anonymous: # try: # # find the User's record and delete it # idvisit = VisitSaleMonitor.by_visit_key(visit.key) # except SQLObjectNotFound: # pass # else: # idvisit.destroySelf() # return try: # see if the salemonitor obj has already been created salevisit = VisitSaleMonitor.by_visit_key(visit.key) except SQLObjectNotFound: # not found, so this must be the first visit salevisit = VisitSaleMonitor(visit_key=visit.key) if path in ('/', '/index') and not salevisit.pitch_time: salevisit.pitch_time=datetime.now() elif path=='/sale_complete' and not salevisit.sale_time: salevisit.sale_time=datetime.now() def add_sale_visit_plugin(): log.info('Starting SaleVisitPlugin') turbogears.visit.enable_visit_plugin(SaleVisitPlugin()) turbogears.startup.call_on_startup.append(add_sale_visit_plugin)
And that’s it. Import salemonitor into your controllers.py, and you should be logging exactly when and what a visitor is doing. You now have information in your database that can be extracted via SQLObject queries or normal SQL.
It isn’t hard to see how one might extend this simple example to do more complex click tracking and analysis. For instance, it could easily be extended to track how many visitors start entering their billing information, and then back out.
For general information on how to use the visit framework see Using the Visit Framework.
If you want to log more information about logged-in users, like e.g. the user name or permissions, have a look at the Identity documentation.
If you want to store visit object in a different storage backend, customize how visit objeccts are created and updated or perform any house-keeping tasks while the visit framework is running, you need to implement your own visit manager.
TurboGears comes with two standard visit managers, one with a SQLObject backend and another for SQLAlchemy. Which one is used is determined by the configuration setting visit.manager, whose value is normally sqlobject or sqlalchemy. When you want to use a custom visit manager, you have to register it as a plugin for the turbogears.visit.manager entry-point via the setup.py file of the package which includes the visit manager class.
For example, if your custom visit manager class is MyVisitManager in the module mypackage.myvisit, you would add the following to the setup call:
setup( # [...] entry_points=""" [turbogears.visit.manager] my_visit_mamager = mypkg.myvisit:MyVisitManager """, # end new )
You can then use my_visit_manager as the value for the visit.manager configuration setting.
Since TurboGears 1.1 it is also possible to specify the visit manager class directly with visit.manager using a fully-qualified dotted-path notation, for example:
visit.manager = 'mypkg.myvisit.MyVisitManager'
The visit manager is responsible for keping track of visits, creating new ones, updating existing ones and handle the communication with the storage backend. Custom visit managers should be sub.classed from one of the standard visit managers (turbogears.visit.sovisit.SqlObjectVisitManager or turbogears.visit.savisit.SqlAlchemyVisitManager) or the abstract base class in turbogears.api.BaseVisitManager. The must provide the following methods:
Should return an existing Visit object for this key.
Should return None if the visit doesn’t exist or has expired.
Since the visit manager runs i its own thread, care should be taken that updates to the storage backend are always made as atomic transactions. | http://www.turbogears.org/1.0/docs/Visit/Extending.html | CC-MAIN-2014-15 | en | refinedweb |

THE SQL Server Blog Spot on the Web
I have been stung by this scenario a few times, using SQL Server's typical sliding window to remove old backup files:
If you want to have a point-in-time set of backups in near-line storage, this will not do, as you have an old Full backup, then a gap, then some transaction log backups that you can't restore.
In the past, I've created various workarounds for this, but they usually involved some process external to SQL Server, and an extra script or executable, and perhaps even xp_cmdshell from SQL Agent. Kluges at best. Enter SQL Server 2005 and CLR. CLR integration, for all the controversy surrounding it, seems ideal to me for this type of thing - I need a utilitarian process that can interact with the OS, but that is safer than the shell and can be code-signed and so on. The .NET framework is a perfect fit.
Before I delve into the details, I want to note some additional requirements: I've always worked in shops with a third-party backup compression tool such as Litespeed or Red Gate SQL Backup, so it's important that the solution work no matter how the backups get onto the disk. Second, I need to be able to disable (perhaps "leave disabled" is more accurate) xp_cmdshell in the configuration of SQL Server for security purposes. Finally, the solution should work from "inside" familiar SQL Server tools, like SQL Agent, so other DBAs don't face some cryptic solution that isn't simple and easy to find and understand.
What I am after is a method that can more selectively delete the old backup files from disk, but take into account the dependencies between them, so that if there are full backups and differentials and log backups, I will always preserve a working sequence of files. I settled on a CLR stored procedure that can examine the backup files in a directory, and sort out this dependency before removing old files.
A simple outline for this procedure looks something like this:
In C#, with classes like FileInfo from the .NET Framework, this is quite simple to put together. I elected to use the file names to identify which files depend on which others, mainly because of the first requirement above that the procedure work on any type of native or third-part backup files. This does introduce requirements for naming conventions that might be avoidable if we could reliably read the data in the files themselves (i.e. if these were all SQL Server native files), but the conventions can be simple, and I customarily name files this way in any case. The names have to follow this pattern:
<database name> <anything you like>_<chronological datetime>.<extension>
<database name> <anything you like>_<chronological datetime>.<extension>
For example:
mydatabase_FullBackup_20090101.bak
or
mydatabase_2009-01-21.bak
or
myDatabase_arbitraryDescription_20090101023015.foo
mydatabase_FullBackup_20090101.bak
or
mydatabase_2009-01-21.bak
myDatabase_arbitraryDescription_20090101023015.foo
The only important features are that the file names begin with the database name, end with an underscore (_) followed by a string representing a datetime that sorts in dictionary order, and that the extensions are unique for backup, log backup, and differential backup. Each set of files, per database, should be in its own folder to prevent the possibility of file names colliding.
The solution is a fairly short C# function. I began by firing up Visual Studio 2005 and creating a solution with the C# SQL Server Project type. Within the new project I added a new Stored Procedure item, and that provided a template for a new CLR stored procedure, with the appropriate references and basic structure.
Within the Stored Procedure template, I created code following the basic outline above. First I set up arguments for the function to receive when the user calls the stored procedure, including the database name, folder to search, how many backups to keep, what the file naming convention is, and so on. The trick to the method signature is that the arguments have to be of .NET types that match the SQL Server data types a Stored Proc will provide. B.O.L. has a very useful chart of what SQL Server types (varchar(), for example) map to what C# types (SqlString). Otherwise, the statement to create a C# function and the T-SQL statement to create a procedure are very similar:
[Microsoft.SqlServer.Server.SqlProcedure]
public static int DeleteAgedBackupFiles(SqlString databaseName,
SqlString directory,
SqlInt32 fullBackupsToRetain,
SqlString fullBackupExt,
SqlString trnBackupExt,
SqlString diffBackupExt,
SqlBoolean archivedFilesOnly) {
}
Next, DirectoryInfo and FileInfo provide ready-to-use functionality to interrogate files and folders, so I leveraged those to get lists of the files in the folder indicated, for the database indicated, and put the file lists into standard .NET Arrays:
DirectoryInfo folder = new DirectoryInfo(directory.Value);
FileInfo[] bakFiles;
FileInfo[] diffFiles;
FileInfo[] trnFiles;
String bakPattern = databaseName.Value + "*." + fullBackupExt.Value;
String trnPattern = databaseName.Value + "*." + trnBackupExt.Value;
String diffPattern = databaseName.Value + "*." + diffBackupExt.Value;
try
{
bakFiles = folder.GetFiles(bakPattern);
trnFiles = folder.GetFiles(trnPattern);
diffFiles = folder.GetFiles(diffPattern);
}
Having lists of the files in arrays makes it pretty simple to run through them and perform the needed work, with for() or foreach() loops. But one tricky bit first: if the arrays were ordered, it would save a lot of extra effort comparing file names. Like most things .NET, basic tasks practically always have a provided object or method, and so, unsurprisingly, Array has a built-in Sort. No need to reinvent that wheel. The only issue that is perhaps less than intuitive is that the sort function has to be told how to order the objects in the array, using a "helper" in the form of a Comparer. A comparer is just a way for the sort function to compare two objects and determine which is first and which is second in the order you intend. Making a comparer takes just a few lines of code. In this case we want the files in standard dictionary order. That means that if the file names are sorted with a standard string sort, we have what we need. A simple version of that comparer is:
public class CompareFileNames : IComparer
{
public int Compare(object x, object y)
{
return ((FileInfo)x).Name.CompareTo(((FileInfo)y).Name);
}
}
In plain English, this function says, given two FileInfo objects, fetch out the file names and compare them as strings. The order of the strings is the order we want. Having this class included in the code allows us to sort an array of file objects with one line:
Array.Sort(bakFiles, new CompareFileNames());
Once the Arrays are ordered, I can do something like this to remove the oldest files:
// Delete every full backup file older than the file that satisfies the
// FullBackupsToRetain argument, taking into account the Archive attribute:
if (bakFiles.Length > 0)
{

Similar loops can process the arrays of differential and log backup files, selectively deleting the appropriate files. That is the basic idea driving the whole stored procedure. I won't go into every detail here, but instead offer the entire function in the code listing at the end of this post.
Once the procedure is written, the next step is to deploy it. This is where things perhaps get less familiar for the typical DBA, but I found this fairly simple once I did some reading. If .NET CLR code called from SQL Server is going to operate outside the SQL Server itself - for example, deleting files from the file system - it's important that the code be secure. For that reason, the SQL Server team created some special security categories for CLR procedures, and rules around those. In simplified terms, you have to do these things:
The first time through I found this a little bumpy, but it's not too bad once you've done it once or twice, and each tool (Visual Studio and T-SQL) has methods that simplify the process. I won't repeat all the detailed instructions here, because others have, and it's in B.O.L. Here is a simple reference I found helpful, by Jonathan Kehayias:
I agree with his advice that signing the code is better and more secure than the "Trustworthy" option within SQL Server. Plus, it's really not any more work.
That's all there is to it. Extending SQL Server to do essentially anything that .NET libraries can do is quite straightforward, and might be a safer alternative to those xp_cmdshell-based jobs lurking around on your servers.

What is the login for?
It can not be the job owner, can not be used "with execute as"?
The login enables code-signing the .NET assembly. It's basically so that SQL Server can validate the assembly with a key before executing it. If there were no key like the one managed by that login, some malicious code or person could potentially alter the assembly, sneak the new version in and the server might execute it.

I'm quite aware that I seem not to get something about layout modifiers. I thought that adding a hook was just like: layoutModifier :: Layout a -> Layout a layoutModifier cl@(Layout {doLayout = dl , modifyLayout = ml}) = Layout {doLayout = dl , modifyLayout = modLay} where modLay sm | Just e <- fromMessage sm = do handle_event e ml sm | otherwise = ml sm handle_event e@(AnyEvent {ev_event_type = t}) | t == whatEverEvent = do io (putStrLn "Hello World") >> return () -- but focus w ??? handle_event _ = return () But if I change "putStrLn Hello..." with focus w, that is to say, if I change the stack of windows what should I do next? runlayout (with the need of recalculating the screen rectangle), for instance? This is not clear to me and I seem not to be able to get it only by studying the code (your code actually). Self-modifying layouts and layout transformers is precisely what I want to understand.

droid = android.Android()
message = raw_input("search:")
droid.webViewShow("",message)
Is it any where near being right?
Also if anyone could point me to a good tutorial for making apps with python 2.x would be much appreciate as that is what i would like to learn to do(iv tried searching but all i get is pygame tutorials i want to do apps and be able to do in on my android) kivy maybe, i dont know what it is but iv heard its something to do with apps.
So basically is that code anywhere near being right?
Is kivy a different language if not a tutorial on using it?
I think thats it. Thanks anyone who answers | http://www.python-forum.org/viewtopic.php?p=4131 | CC-MAIN-2014-15 | en | refinedweb |

Same issue in ipc.py
Not sure about the performance impact of this patch, but it should do the trick.
Bruce: if we don't import the module hashlib, then the hashlib name is undefined. If you subsequently say if hashlib, you're going to throw a NameError
Lame error on my part then ... Your fix for that part looks good.
Found another fun one: we use finally in test_protocol.py and test_schema.py
Not important, but wouldn't
{{
try:
from hashlib import md5
except ImportError:
from md5 import md5
}}
be simpler and preferable? or "as compute_md5" if you're stuck on that.
Michael: I'll check it out. The code currently calls hashlib.md5() or md5.new(), so your idea would not work as it currently stands, as the latter appears to use a factory. md5.new and md5.md5 are the same thing.
Yep, that's what I wanted to confirm once I got in front of a computer. Your way is certainly cleaner, so I'll update the patch.
I've addressed most of the issues (thanks for the comments!) but I'm stuck on how to modify our use of the uuid module, which appeared in Python 2.5. I've asked on Quora about the best way to generate RFC 4122-compliant UUIDs in Python 2.4:'s-the-best-way-to-generate-RFC-4122-compliant-UUIDs-in-Python-2.4. If you happen to know the answer, please let me know!
Okay, added uuid_24.py by taking the source from. I need to figure out the right way to license it, but I'd love it if someone else could take this patch for a spin on a Python 2.4 installation and see if it works for them.
The uuid code is under the PSF license:
This requires that we include a copyright statement and a copy of the license in our distributions. HTTPD provides a good model. Look at the end of:
So, in our LICENSE.txt file, we should add sections at the end for sub-components whose licenses differ, providing the relative path for each such subcomponent followed by its copyright and licence. We already have one such appended license, but it should probably be amended to provide the path, and we should add an introductory paragraph for all sub-component licenses. In short, we should model the structure of HTTPD's LICENSE.
CentOS 5 is still shipping it, so we should make it work.
Current issue is our use of struct.Struct objects in io.py. | https://issues.apache.org/jira/browse/AVRO-588?focusedCommentId=12884992&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel | CC-MAIN-2014-15 | en | refinedweb |

PHP is largely a very flexible templating system with support for complex expressions and a huge catalogue of predefined procedures available in a flat namespace. The manual exists for the above functionality, and makes the assumption that you invent your 'web environment' ad hoc. Indeed the situation with the multitude of Python web CMSes and frameworks could improve, but I don't think you face half the difficulty in picking a specific Python one over a specific PHP one. Again, PHP CMSes tend to advertise their flashy featuresets and latest 'mods', whereas Python CMSes tend to list more practical goals. Take an example, the Google descriptions for Plone and PostNuke: Description: The Postnuke Content Management System offers full CSS support and HTML 4.01 transitional compliance... Description: Content Management Framework (CMF) that runs on top of Zope. Can be used as an intranet server, a...

"Obvious", being my favourite word for the month, could maybe have been put to good use previously. A quick search of Python.org will bring you up the DB-API docs, which is precisely what happened the first time I went searching for information about Python and databases. The same cannot be said for PHP, where you'll either get a tutorial for how to use the raw MySQL/Psql/Oracle API functions exported by the PHP engine, or you'll get faced with a choice between a plethora of DB 'middlewares'. > The site that I worked on spent TWO MILLION U.S. DOLLARS on its web > server hardware.

And while the UI is very similar regardless of the language and framework you're using, actually getting <a target="_blank" rel="external" href="">New Relic</a> set up can be radically different. Today, we will look at how to monitor a PHP application using New Relic. More specifically, we will set up a basic <a target="_blank" rel="external" href="">WordPress</a> installation and get some performance data about it, in the New Relic dashboards.<br></p><p>Getting New Relic set up for Ruby is very much environment agnostic. We simply add the agent gem to our application at which point no matter how we deploy our app (<a target="_blank" rel="external" href="">Passenger</a> + <a target="_blank" rel="external" href="">Apache</a>, <a target="_blank" rel="external" href="">Thin</a> + <a target="_blank" rel="external" href="">Nginx</a>. <br></p><p>Let's set up a sandbox for us to play with (using an <a target="_blank" rel="external" href="">EC2 instance</a>) and get a basic WordPress install up and running.<br></p><h2>Setting Up Our Sandbox<br></h2><p>We won't go into too much detail here as most of the things we need to do are well-documented elsewhere. But, here is a basic outline.<br></p><p>We need to launch an EC2 instance with <a target="_blank" rel="external" href="">Ubuntu Server 12.04 LTS</a> on it. If you don't want to set up an EC2 instance, you can just create a virtual machine instead using <a target="_blank" rel="external" href="">VirtualBox</a> (or your VM tool of choice). If you're setting up an EC2 instance, you need to remember to do the following:<br></p><ul><li>download your key (if you've created a new one during the set up process), so that you can SSH into your instance</li><li>add an extra rule to any security group you give to your instance to allow HTTP connections to the instance (so that we can actually access our WordPress blog via the browser later on)</li></ul><figure class="post_image"><img src="" alt=""></figure><p>Aside from that, everything else should be pretty straight forward and you should end up with a running instance (or virtual machine) that's ready for the next step.<br></p><p>We now need to install Apache, PHP and <a target="_blank" rel="external" href="">MySQL</a>. With Ubuntu Server, it should be a simple matter of running the following commands:</p><pre class="brush: bash">sudo apt-get install tasksel sudo tasksel install lamp-server</pre><p. </p><p>First check that Apache is installed:</p><pre class="brush: bash") ...</pre><p>Secondly, check that we have PHP:</p><pre class="brush: bash" ...</pre><p>And then check that we have MySQL:</p><pre class="brush: bash">ubuntu@ip-10-145-246-196:~$ mysql --version mysql Ver 14.14 Distrib 5.5.35, for debian-linux-gnu (x86_64) using readline 6.2</pre><p>We may also need to check that PHP is actually enabled in our Apache config, but since we installed <code class="inline">lamp-server</code> using <code class="inline">tasksel</code> we can be pretty sure that it is (and we can always do a quick <code class="inline">phpinfo()</code> script if we really want to check).</p><p>We can now install WordPress. Before we actually download it, we need to set up a database for it so. We can just follow the <a target="_blank" rel="external" href="">instructions from the Codex</a>:</p><pre class="brush: bash"</pre><p>I am going to call our new installation <code class="inline">myblog1</code> (so the database for it is also named <code class="inline">myblog1</code>). We now need to run the following commands to get our blog running (don't forget to <code class="inline">sudo</code> when necessary):</p><pre class="brush: bash">cd /var/www wget tar -xzvf latest.tar.gz mv wordpress myblog1 cd myblog1 mv wp-config-sample.php wp-config.php</pre><p>Now fill in your database name, username and password into the config file (the hostname is <code class="inline">localhost</code> which is there by default). At this point you should be able to go to your browser, hit the right URL (in my case <a href=""><code class="inline"></code></a>) and WordPress will do its thing (it might not hurt to restart Apache before doing this <code class="inline">sudo apache2 service restart</code>).</p><p>Our sandbox is now complete and we can get started with installing New Relic.<br></p><h2>Installing New Relic<br></h2><p>As I mentioned previously, the PHP New Relic agent resides on the box, it therefore makes sense that you can install it using the operating system's package manager (<code class="inline">apt-get</code> since we're using Ubuntu). The first thing to do is to import the New Relic repository key:</p><pre class="brush: bash">wget -O - | sudo apt-key add -</pre><p>Now we add the New Relic repository itself to the system: </p><pre class="brush: bash">sudo sh -c 'echo "deb newrelic non-free" > /etc/apt/sources.list.d/newrelic.list'</pre><p>At this point, we can use standard <code class="inline">apt</code> commands to install the agent:</p><pre class="brush: bash">sudo apt-get update sudo apt-get install newrelic-php5</pre><p>This fetches the PHP agent package from the repository and puts the agent install script on the system. The script is called <code class="inline">newrelic-install</code> and it lives in <code class="inline">/usr/bin</code>, so you should be able to run in from anywhere. The script is also somewhat unfortunately named, as you can use it to both install and uninstall New Relic from your system. In order to install New Relic, we need to run:</p><pre class="brush: bash">newrelic-install install</pre><p>The script is interactive and will ask you to input your license key. You can find this by pressing the <b>big red button</b> when you're setting up a new PHP application within the New Relic UI.</p><figure class="post_image"><img src="" alt=""></figure><p.<br></p><p>If everything goes well, you should see the following message:</p><pre class="brush: bash">New Relic is now installed on your system. Congratulations!</pre><p>The script will then print out some extra information for you including the location of the log files:</p><pre class="brush: bash">/var/log/newrelic/newrelic-daemon.log /var/log/newrelic/php_agent.log</pre><p>As well as the fact that you need to restart your web server (and PHP-FPM if you're using it).</p><p>If you do restart your server and tail the daemon log, you should see something like this:<:'</pre><p>Something named <i>PHP Application</i> <i>PHP Application</i>. </p><p.</p><h2>What a Healthy Install Looks Like<br></h2><p>There are two parts to the New Relic PHP agent. The first is a PHP extension, it's a shared object called <code class="inline">newrelic.so</code>. If we look at the agent configuration file:</p><pre class="brush: bash">/etc/php5/cli/conf.d/newrelic.ini</pre><p>We can see it listed right at the top:</p><pre class="brush: bash">;./etc/init.d/newrelic-daemon stop</pre><p).</p><h2>Configuring the Agent (and the Proxy Daemon)<br></h2><p>We've already seen the New Relic PHP agent configuration file <code class="inline">/etc/php5/cli/conf.d/newrelic.ini</code>. Both the agent and the daemon are configured using this file.<br></p><p>This file is very well documented with all the options and their default values listed. Let's talk about the format of this file. The New Relic Ruby agent can be configured via <a target="_blank" rel="external" href="">YAML</a>, which is a well-known format. The PHP agent is simply a text file, but we need a little bit of structure. Each variable in the file has one of four types (String, Boolean, Number, Duration). String and number are self-explanatory, boolean values can be <code class="inline">true</code>, on or <code class="inline">1</code> to indicate truthiness and <code class="inline">false</code>, off or <code class="inline">0</code> to indicate falsiness. Durations are strings with a particular format, for example: <code class="inline">"1w3d23h10m"</code> indicates one week, three days, 23 hours and ten minutes. The values for durations can be as granular as microseconds.<br></p><p.<br></p><p>For example, the most common configuration variable is <code class="inline">`newrelic.appname`</code>. This variable is a String type, it has a default value of <i>PHP Application</i> (now we know why we saw that value in the log file after we installed the agent and restarted the server). The scope of this variable is PERDIR which gives us an idea about how to override the application name for our WordPress blog. <br></p><p>There are many other variables controlling things like the location of the log files, whether or not sql queries are recorded, the log level of the log output and so . I encourage you to study the <code class="inline">newrelic.ini</code> file to familiarise yourself with the options.<br></p><h2>Configuring a Separate App for Our WordPress Blog <br></h2><p>We want to see a separate app in the New Relic UI for our WordPress blog, so let's see how we can get that going. Your options for per directory configuration are different depending on your stack, if you're using <a target="_blank" rel="external" href="">PHP-FPM</a>, the steps are different than if you're using Nginx. In our case, since we're running straight Apache, we have two options.<br></p><p>Firstly, if we have a virtual host for our app, we can insert an <code class="inline">IfModule</code> block into our virtual host block and modify the name of the app there:</p><pre class="brush: bash">... <IfModule php5_module> php_value newrelic.appname "My Blog 1" </IfModule> ...</pre><p>But I don't have a special virtual host just for the blog, so the other option is to use a <code class="inline">.htaccess</code> file. Ensure that you actually allow <code class="inline">.htaccess</code> files, by dumping the following in to your main virtual host:</p><pre class="brush: bash"><Directory /var/www/myblog1> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory></pre><p>We can now put an <code class="inline">.htaccess</code> file in the top level directory of our blog and put the following in it:</p><pre class="brush: bash">php_value newrelic.appname "My Blog 1"</pre><p>The format is exactly the same as if I was putting it into the <code class="inline">IfModule</code> block. Now we just need to bounce our server. If we tail the daemon logs when the server restarts, we will see the following:<:' 2014-03-23 06:07:58.768 (2008/connector) info: ['My Blog 1'] 'Reporting to:'</pre><p>The <i>PHP Application</i> is still there, but now it has a friend which is our WordPress blog. And here it is in the UI:</p><figure class="post_image"><img src="" alt=""></figure><p).<br></p><h2>Updating the Agent & Daemon<br></h2><p>New Relic is a complex piece of software and it's good to keep it up to date as bugs are fixed regularly and new features are added. Since we installed everything using <code class="inline">apt-get,</code> keeping things up to date is easy. We simply do the same thing we did to install it:</p><pre class="brush: bash">apt-get update apt-get install newrelic-php5</pre><p>If we haven't installed another PHP on the system, we now simply need to restart our server and we'll be up to date. If there is a new PHP, we may need to re-run the <code class="inline">newrelic-install</code> script.</p><p.<br></p><h2>Conclusion<br></h2><p <a target="_blank" rel="external" href="">Cake</a>, <a target="_blank" rel="external" href="">Symphony</a> and <a target="_blank" rel="external" href="">Laravel</a> (version 4 and up). It is also possible to use New Relic with an unsupported framework, but you will have to put in some serious effort to get the metrics to make sense.-14T15:00:13.175Z 2014-04-14T15:00:13.175Z Alan Skorkin tag:code.tutsplus.com,2005:PostPresenter/cms-20626 Alternatives to Prefixr <p>Awhile ago, the awesome Jeffrey Way created a tool called <a href="">Prefixr</a>.</p> <p>Unfortunately, now that the site has gone the way of the dodo bird and after having several users ping us about it, we wanted to provide some alternatives that can help provide similar capabilities.</p> <h2>The Express Prefixr Library</h2> <p>The first option which is closest to the functionality of Prefixr is a site called <a href="">Express Prefixr</a>. This was created by the awesome <a href="">TJ Holowaychuk</a> who apart from being an expert on Node.js development, also created the <a href="">Express</a> web application framework for <a target="_self" href="">Node.js</a>. </p> <p>With Express Prefixr, you're presented with two <i>textarea</i> fields, one for entering your styles and the second to receive the prefixed output from the service. This is very similar to the way that Prefixr worked:</p><figure class="post_image"><img src="" alt=""></figure> <p>To test this out, I'm taking the same code sample that Jeffrey used in his original article:</p> <pre class="brush: css">; } } </pre> <p>Then pressing on the "<b>Prefix it!</b>" button, I can immediately get my prefixed styles sent to me:</p><figure class="post_image"><img src="" alt=""></figure> <p>Here's the complete result:</p> <pre class="brush: css">; } } </pre> <p>Taking this further, Express Prefixr also provides an API that you can leverage to integrate into your applications or use third party tools like <code>curl</code>. So taking the following snippet:</p> <pre class="brush: bash">curl -d css='body { border-radius: 10px}'</pre> <p>And pasting it into my <code>terminal</code> window gives me the following results:</p> <pre class="brush: bash">reys-mbp:~ rey$ curl -d css='body { border-radius: 10px}' body { -webkit-border-radius: 10px; -moz-border-radius: 10px; -ms-border-radius: 10px; -o-border-radius: 10px; </pre> <p>One final great thing about Express Prefixr, is that the <a href="">code is available on GitHub</a> allowing you to easily fork it and customize the software to your needs.</p> <h2>The Autoprefixer Library</h2> <p>The next option is actually designed to integrate more so into your workflow, rather than being a visual UI tool. <a href="">Autoprefixer</a> does in fact add prefixes where appropriate by using rules provided by the popular site, <a href="">Can I Use</a>. Autoprefixer's slogan is:</p> <p>"Write your CSS rules without vendor prefixes (in fact, forget about them entirely)"</p> <p>And it holds true. What this means is that in your stylesheets, you can focus on using the standards-based syntax and Autoprefixer will handle adding in the prefixed rules if necessary.</p><p>Let's look at some code:<br></p> <pre class="brush: css">:fullscreen a { transition: transform 1s }</pre> <p>The above code will be updated by Autoprefixer to the following:</p><pre class="brush: } </pre><p>Take a close look at the syntax. Notice that the <code>transition</code> rule was pretty much left alone except for the addition of the two Webkit-specific entries. That's because Autoprefixer only applies vendor prefixes when it's appropriate. In this case, <code>transition</code> is widely supported in modern browsers and doesn't really need to be prefixed.</p> <p>But, the <code><a href="">:fullscreen</a></code> pseudo-class is still evolving and does need to be properly prefixed. Autoprefixer, using the Can I Use data, is smart enough to determine when to prefix something based on a browser's level of support for a feature. Very cool!</p> <p>The thing to note is that Autoprefixer is meant to be incorporated into your normal deployment workflow. It's not a client-side library and you leverage it via any number of third party integrations. This includes:</p> <ul> <li>Grunt via the <a href="">grunt-autoprefixer plugin</a></li> <li>Compass via the <code>autoprefixer-rails</code> gem</li> <li>Stylus via the <a target="_self" href="">autoprefixer-stylus plugin</a></li> <li>Broccoli via the <a href="">broccoli-autoprefixer plugin</a></li> <li>Sublime Text with the <a href="">sublime-autoprefixer plugin</a></li> </ul> <p>And so many more options. Even the new Atom Editor now has the <a href="">atom-autoprefixer package</a> which shows that Autoprefixer is well-maintained.</p> <p>If you'd like to see Autoprefixer in action, jump on over to the following <a href="">demo</a> and add a bunch of CSS rules that you've traditionally had to vendor prefix and see how it works for you. </p> <h2>The -Prefix-Free Library</h2> <p>The final option is a great client-side library by <a href="">Lea Verou</a> called <a href="">-prefix-free</a>..</p> <p>The key difference between this and the two others I mentioned previously is that -prefix-free is a JavaScript library that looks at your stylesheets in runtime and adds the vendor prefixes when needed. </p> <p>Using the library is as simple as adding the following line to the <code>head</code> of your page:</p><pre class="brush: html"><script src="prefixfree.js"></script></pre> <p>No, seriously. That's it. The library handles the processing of every stylesheet in <code>link</code> or <code>style</code> elements and adds a vendor prefix where needed. This is especially useful for sites that are already deployed and it may not be possible to go back and update it.</p> <p>It also has solid browser support being compatible with IE9+, Opera 10+, Firefox 3.5+, Safari 4+ and Chrome on desktop and Mobile Safari, Android browser, Chrome and Opera Mobile on mobile.</p> <h2>Hoping Vendor Prefixes Go Away</h2> <p>It's great to have alternatives to Prefixr and these solutions certainly fit the bill. Ultimately, though, vendor prefixes have become more complicated than they're worth and with many developers not respecting the original intent of them (for example, to designate <i>experimental</i> features) and leveraging them in production systems, hopefully they'll go away in the near future. </p><p>Thankfully, Google <a href="">mentioned</a> when they announced their Blink rendering engine, that they would be shifting to a feature-flag model which would hide experimental features behind hard-to-set flags which aren't accessible via code.

The server side code was only PHP at the moment, so it went in to the <code>php</code> directory. We wrap everything into around 30 files and everything was OK. </p> <h2>The Journey</h2> <p>During the period of a few months, we were trying different concepts and changed the project's code several times. From the current point of view, I could spot four big issues which we met.</p> <h3>Problem #1 - Too Many Badly Structured Files</h3> <p.</p><figure class="post_image"><img alt="" src=""></figure> <p>For example, the CSS styles for the <em>about</em> page were in <code>css/about/styles.css</code>. The JavaScript in <code>js/about/scripts.js</code> and so on. We used a PHP script which concatenates the files. There were, of course, parts of the site that were on several pages and we put them in <code>common</code> directories. This was good for a while, but it did not work well for long because when the directories became full, it was slow to modify something. You had to search for three different directories to find what you needed. The site was still mainly written in PHP.</p> <h3>Problem #2 - The Big Turning Point or How We Messed Things Up</h3> <a href="">MEAN stack</a>). </p> <h3>Problem #3 - A Tough Working Process</h3> <p>We used <a href="">GruntJS</a> for a while, but migrated to <a href="">Gulp</a>.:</p><figure class="post_image"><img alt="" src=""></figure> .</p> <h3>Problem #4 - Angular vs. Custom Code</h3> <p <a href="">CSS preprocessor</a>. The project goes really, really fast. Very soon I ported my library for client side usage. Line by line, it was transformed to a small framework, which we started integrating into the project.</p><h4>Why Create a New Framework?</h4> <p. </p><p. </p><p>I like the words of <a href="">Jeremy Keith</a>, in his talk <a href="">The power of Simplicity</a>,. </p><p>We also tried Ember, but it did not work, because it is heavily based on its routing mechanisms. Backbone was a nice choice and it was the closest thing to our vision. However, when I introduced <a href="">AbsurdJS</a> we decided to use it.</p> <h2>What AbsurdJS Did For Us</h2> <p><a href="">AbsurdJS</a> was originally started as a <a href="">CSS preprocessor</a>, expanded to an <a href="">HTML preprocessor</a>.</p> <h3>Divide and Rule</h3> <p:</p> <pre class="brush: javascript">var absurd = Absurd(); var MyComp = absurd.component('MyComp', { constructor: function() { // ... } }); var instance = MyComp(); </pre> <p><code>absurd.component</code> defines a class. Calling the <code>MyComp()</code> method creates a new instance.</p> <h3>Let's Talk to Each Other</h3> <p>Having all these small components, we needed a channel for communication. The observer pattern was perfect for this case. So, every component is an event dispatcher.</p> <pre class="brush: javascript">var MyComp = absurd.component('MyComp', { doSomething: function() { this.dispatch('something-happen'); } }); var instance = MyComp(); instance.on('something-happen', function() { console.log('Hello!'); }); instance.doSomething(); </pre> <p.</p> <h3>Controlling the DOM</h3> <p>Along with the PHP served markup, we had dynamically created DOM elements. This means that we needed access to the existing DOM elements or new ones, that will be later added to the page. For example, let's say that we have the following HTML:</p> <pre class="brush: html"><div class="content"> <h1>Page title</h1> <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p> </div></pre> <p>Here is a component which retrieves the heading:</p> <pre class="brush: javascript">absurd.component('MyComp', { html: '.content h1', constructor: function() { this.populate(); console.log(this.el.innerHTML); // Page title } })(); </pre> <p>The <code>populate</code> method is the only <em>magic</em> method in the whole library. It does several things like compiling CSS or HTML, it binds events and such things. In the example above, it sees that there is an <code>html</code> property and initializes the <code>el</code> variable which points to the DOM element. This works pretty good for us because once we got that reference, we were able to work with the elements and its children. For those components that needed dynamically created elements, the <code>html</code> property accepts an object.</p> <pre class="brush: javascript">absurd.component('MyComp', { html: { 'div.content': { h1: 'Page title', p: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.' } }, constructor: function() { this.populate(); document.querySelector('body').appendChild(this.el); } })(); </pre> <p <a href="">templating engine</a>.</p> <pre class="brush: javascript">absurd.component('MyComp', { html: { 'div.content': { h1: '<% this.title %>', ul: [ '<% for(var i=0; i', { li: '<% this.availableFor[i] %>' }, '<% } %>' ] } }, title: 'That\'s awesome', availableFor: ['all browsers', 'Node.js'], constructor: function() { this.populate(); document.querySelector('body').appendChild(this.el); } })(); </pre> <p>The result is:</p> <pre class="brush: html"><div class="content"> <h1>That's awesome</h1> <ul> <li>all browsers</li> <li>Node.js</li> </ul> </div></pre> <p>The <code>this</code> keyword in the expressions above, points to the component itself. The code between <code><%</code> and <code>%></code> is valid JavaScript. So, features like computed properties could be easily developed directly into the template's definition. Of course, we are able to use the same template engine with already existing markup. For example:</p> <pre class="brush: html"><div class="content"> <h1><% this.title %></h1> <ul> <% for(var i=0; i&lt;this.availableFor.length; i++) { %> <li><% this.availableFor[i] %></li> <% } %> </ul> </div></pre> <p>... could be controlled with the following component (the result is the same):</p> <pre class="brush: javascript">absurd.component('MyComp', { html: '.content', title: 'That\'s awesome', availableFor: ['all browsers', 'Node.js'], constructor: function() { this.populate(); } })(); </pre> <p>Anyway, the point is that we were able to define templates or create such from scratch. We are also able to control the data that is injected in an easy and natural way. Everything is just properties of the good old JavaScript object. </p> <h3>What About the Styling?</h3> <p. </p> <p>Then I thought, what will happen if we do the same thing with the CSS. It was of course possible because AbsurdJS was a CSS preprocessor and could produce CSS. We just got the compiled string, create a new <code>style</code> tag in the <code>head</code> of the current page and inject it there.</p> <pre class="brush: javascript">absurd.component('MyComp', { css: { '.content': { h1: { color: '#99FF00', padding: 0, margin: 0 }, p: { fontSize: '20px' } } }, html: '.content', constructor: function() { this.populate(); } })(); </pre> <p>Here is the <code>style</code> tag which is produced:</p> <pre class="brush: html"><style id="MyComp-css" type="text/css"> .content h1 { color: #99FF00; padding: 0; margin: 0; } .content p { font-size: 20px; } </style></pre> <p. </p> <h3>That Awkward Moment</h3> <p>... when everything works perfectly but you feel that something is wrong</p> <p?".</p><figure class="post_image"><img alt="" src=""></figure> <p>And what we did, is a little bit different. It looks more like the picture below.</p><figure class="post_image"><img alt="" src=""></figure> <p. </p><p. </p><p>We, as developers, will have to develop such components and probably connect with and use such components written by others. Projects like <a href="">AbsurdJS</a> or <a href="">Polymer</a> are showing that this is possible and I encourage you to experiment in this direction. </p> <h2>Back to Reality</h2> <p.</p> <p.</p> <h2>Conclusion</h2> <p>If you found this tutorial interesting, check out the official page of <a href="">AbsurdJS</a>. There are guides, documentation, and articles. You can even try the <a href="">library online</a>. <a href="">available at-07T14:00:09.593Z 2014-04-07T14:00:09.593Z Krasimir Tsonev tag:code.tutsplus.com,2005:PostPresenter/cms-20563 Creating an RSS Feed Reader With the MEAN Stack <p>This article is a continuation of <a href="">Introduction to the MEAN Stack</a>. The previous post covered the installation of the MEAN stack and also presented what we ended up with in terms of its directory structure, after installation. Now it's time for some actual coding!</p> <h2>What We'll Be Building</h2> <p>We will be building an RSS feed reader using the MEAN stack. The application will allow its user to manage their list of feeds by adding a new feed, deleting an existing one, modifying an existing one and, of course, seeing a list of all the feeds in which the user is interested in.</p> <p>The user has to authenticate in order to have access to the application, so that the feeds of one user are not visible to others and most importantly, to users that are not logged in. As we saw in the <a href="">previous</a> article, the stack comes with a full authentication mechanism already implemented, so we can use it without further modifications.</p> <p>The feed's URLs are stored in a Mongo database on the server so that they are available even after logging off, or after closing the browser.</p> <p>The last feeds are displayed to the user on the main page and they will show the article's title, an excerpt and allow the user to click on the title to read the entire post.</p> <p>The user will also have the possibility to filter the feeds on various criteria.</p> <p>In this first part, we will discuss the implementation of the server part of our application (the backend). We will implement a REST API to respond to the user's requests for viewing, creating, deleting and modifying feeds.</p> <p>Luckily for us, the MEAN stack gives us such an API for handling the articles that can be created. We will modify this API to respond to our need of handling the feed URLs. After all, this is why we are using boilerplate code, to modify and adapt it to the needs of our application. So let's do that!</p> <h2>The Routes</h2> <p>Let's spend a minute and think about what routes our app should to respond to. The picture below shows what we expect to have: </p><figure class="post_image"><img alt="" src=""></figure> <p>Now, let's open the file <code>app/routes/articles.js</code>. If we look at its contents, we see that this is what we want to have, but applied to the articles. So, we have to modify it a little to fit our needs. First, change its name from <code>articles.js</code> to <code>feeds.js</code>. Then modify it as shown below:</p> <pre class="brush: javascript"> // app/routes/feeds.js 'use strict'; var feeds = require('../controllers/feeds'); var authorization = require('./middlewares/authorization'); // Feeds authorization helpers var hasAuthorization = function(req, res, next) { if (req.feed.user.id !== req.user.id) { return res.send(401, 'User is not authorized'); } next(); }; module.exports = function(app) { app.get('/feeds', feeds.all); app.post('/feeds', authorization.requiresLogin, feeds.create); app.get('/feeds/:feedId', feeds.show); app.put('/feeds/:feedId', authorization.requiresLogin, hasAuthorization, feeds.update); app.del('/feeds/:feedId', authorization.requiresLogin, hasAuthorization, feeds.destroy); // Finish with setting up the feedId param app.param('feedId', feeds.feed); }; </pre> <p>For those familiar with the Express framework, this shouldn't be anything new, but just in case, let's go over it real quickly. We start by requiring the <code>feeds</code> controller (which we'll see in a moment) and the authorization middleware (which the MEAN stack gives us).</p> <p>Then we have the <code>hasAuthorization()</code> function, which compares the <code>id</code> of the user who wants to manipulate the feed with the <code>id</code> of the logged in user and returns an error if they are not the same. The <code>next()</code> function is a callback which allows the next layer in the middleware stack to be processed.</p> <p>In the last part, our code exports the routes as described in the table above, implementing the security requirements.</p> <h2>The Models</h2> <p>Creating the application's model using <code>mongoose</code> is a breeze. Rename the <code>app\models\article.js</code> to <code>app\models\feed.js</code> and perform the following modifications:</p> <pre class="brush: javascript"> 'use strict'; /** * Module dependencies. */ var mongoose = require('mongoose'), Schema = mongoose.Schema; /** * Feeds Schema. */ var FeedsSchema = new Schema ({ feedUrl: { type: String, default: '', trim: true }, user: { type: Schema.ObjectId, ref: 'User' } }); /** * Statics */ FeedsSchema.statics.load = function(id, cb) { this.findOne({ _id: id }).populate('user', 'name username').exec(cb); }; mongoose.model('Feeds', FeedsSchema); </pre> <p>We define our database structure here as follows: we will have a feeds table containing a <code>feedUrl</code> string type field and a reference to a <code>user</code> which will store the <code>id</code> of the current logged in user. Notice that we don't handle the creation of an <code>id</code> for our documents here, since this is taken care of for us by the MongoDB system.</p> <p>Finally, we define a <code>load()</code> function that filters the documents in the database based on the <code>id</code> of the current logged in user.</p> <h2>The Controller</h2> <p>The controller is responsible for implementing the functions called by the router, when a specific route is requested. All the necessary functions for the CRUD operations we perform are implemented in the controller. Let's take a look at them one by one and see the implementation details.</p> <p>You should be noticing a pattern by this point. First, don't forget to rename the <code>app/controllers/articles.js</code> file to <code>app/controllers/feeds.js</code>.</p> <h3>Creating a Feed</h3> <p>In order to create a feed we implement the <code>create()</code> function:</p> <pre class="brush: javascript"> /** * Create a feed */ exports.create = function(req, res) { var feed = new Feeds(req.body); feed.user = req.user; feed.save(function(err) { if (err) { return res.send('users/signup', { errors: err.errors, feed: feed }); } else { res.jsonp(feed); } }); }; </pre> <p>First, we create a <code>feed</code> variable based on the <code>Feeds</code> model. Then we add to this variable the reference to the current logged in user to be stored. Finally, we call the model's <code>save</code> method to store the document in the database. Upon error, we return to the signup form since most likely the user is not logged in. If the document is created successfully, we return the new document to the caller.</p> <h3>Modifying a Feed</h3> <pre class="brush: javascript"> /** * Update a feed */ exports.update = function(req, res) { var feed = req.feed; feed = _.extend(feed, req.body); feed.save(function(err) { if (err) { return res.send('users/signup', { errors: err.errors, feed: feed }); } else { res.jsonp(feed); } }); }; </pre> <p>We call Lodash's <code>extend</code> method in order to modify the feed's properties with the ones that came from the user. Then the <code>save</code> method of the model stores the modified data in to the database.</p> <h3>Deleting a Feed</h3> <pre class="brush: javascript"> /** * Delete a feed */ exports.destroy = function(req, res) { var feed = req.feed; feed.remove(function(err) { if (err) { return res.send('users/signup', { errors: err.errors, feed: feed }); } else { res.jsonp(feed); } }); }; </pre> <p>Quite simple, isn't it? The model has a <code>remove</code> method which solved our problem quite easily.</p> <h3>Showing Feeds</h3> <p>Showing all feeds will be the task of the client part of our application. The server will only return the necessary data:</p> <pre class="brush: javascript"> /** * List of Feeds */ exports.all = function(req, res) { Feeds.find().sort('-created').populate('user', 'feedUrl').exec(function(err, feeds) { if (err) { res.render('error', { status: 500 }); } else { res.jsonp(feeds); } }); }; </pre> <p>The code performs a find in the database returning the <code>user</code> and the <code>feedUrl</code>. If <code>find</code> fails, a server error is returned, otherwise all the found feeds will be returned.</p> <p>A single feed is displayed by using the following:</p> <pre class="brush: javascript"> /** * Show a feed */ exports.show = function(req, res) { res.jsonp(req.feed); }; </pre> <p>... which then uses a helper function:</p> <pre class="brush: javascript"> exports.feed = function (req, res, next, id) { Feeds.load(id, function (err, feed) { if (err) return next(err); if (!feed) return next(new Error('Failed to load feed ' + id)); req.feed = feed; next(); }); }; </pre> <p>... that loads a specific feed based on its <code>id</code> (which will come packaged in the URL).</p> <p>The complete code should like this:</p> <pre class="brush: javascript"> // app/controllers/feeds.js 'use strict'; var mongoose = require('mongoose'), Feeds = mongoose.model('Feeds'), _ = require('lodash'); exports.feed = function (req, res, next, id) { Feeds.load(id, function (err, feed) { if (err) return next(err); if (!feed) return next(new Error('Failed to load feed ' + id)); req.feed = feed; next(); }); }; /** * Show a feed */ exports.show = function(req, res) { res.jsonp(req.feed); }; /** * List of Feeds */ exports.all = function(req, res) { Feeds.find().sort('-created').populate('user', 'feedUrl').exec(function(err, feeds) { if (err) { res.render('error', { status: 500 }); } else { res.jsonp(feeds); } }); }; /** * Create a feed */ exports.create = function(req, res) { var feed = new Feeds(req.body); feed.user = req.user; feed.save(function(err) { if (err) { return res.send('users/signup', { errors: err.errors, feed: feed }); } else { res.jsonp(feed); } }); }; /** * Update a feed */ exports.update = function(req, res) { var feed = req.feed; feed = _.extend(feed, req.body); feed.save(function(err) { if (err) { return res.send('users/signup', { errors: err.errors, feed: feed }); } else { res.jsonp(feed); } }); }; /** * Delete a feed */ exports.destroy = function(req, res) { var feed = req.feed; feed.remove(function(err) { if (err) { return res.send('users/signup', { errors: err.errors, feed: feed }); } else { res.jsonp(feed); } }); }; </pre> <h2>Is the REST API Complete?</h2> <p>Well, almost. At this point we do not have the client part of the application implemented in order to prove that the code is working. I didn't present the unit tests for the code either, since it's not so complicated and I wanted to leave it up to you as an exercise.</p> <p>We can test the code using the Postman - REST Client application available on Google Chrome.</p> <h3>Creating a Feed</h3> <p>Install <a href="">Postman</a> if you don't have it already and configure it as follows:</p><figure class="post_image"><img alt="" src=""></figure> <h3>Viewing All Feeds</h3><figure class="post_image"><img alt="" src=""></figure> <h3>Viewing a Single Feed</h3><figure class="post_image"><img alt="" src=""></figure> <p>The remaining parts of the code are easy to verify, so please have some fun with Postman and your new application.</p> <h2>Conclusion</h2> <p>Using a framework or boilerplate code can, in some situations, be useful and make you very productive. As you've seen in this article, implementing the REST API needed for our application was reduced to performing minor modifications to the boilerplate code. Of course for more complex applications, it may be necessary to do more than that, but still, having a starting point can be useful.</p> <p>In the next tutorial, we will take a look at the client part of the application for displaying the data we will request from the server, showing forms for entering new feed URLs, handling events and so-04T14:00:04.955Z 2014-04-04T14:00:04.955Z Gabriel Cirtea tag:code.tutsplus.com,2005:PostPresenter/cms-20527 Refactoring Legacy Code: Part 2 - Magic Strings & Constants <p>Old code. Ugly code. Complicated code. Spaghetti code. Jibberish nonsense. In two words, <em>Legacy Code</em>. This is a series that will help you work and deal with it.</p> <p>We first met our legacy source code in our <a href="">previous lesson</a>. Then we ran the code to form an opinion about its basic functionality and created a Golden Master test suite to have a raw safety net for future changes. We will continue to work on this code and you can find it under the <code>trivia/php_start</code> folder. The other folder <code>trivia/php_start</code> is with this lesson's finished code.</p> <p.</p> <h2>Magic Strings</h2> <p>Magic strings are strings used directly in various expressions, without being assigned to a variable. This kind of string had a special meaning for the original author of the code, but instead of assigning them to a well named variable, the author thought the meaning of the string was obvious enough.</p> <h3>Identify the First Strings to Change</h3> <p>Let's start by looking at our <code>Game.php</code> and try to identify strings. If you are using an IDE (and you should) or a smarter text editor capable of highlighting source code, spotting the strings will be easy. Here is an image of how the code looks like on my display.</p><figure class="post_image"><img alt="" src=""></figure> <p>Everything with orange is a string. Finding each string in our source code is very easy this way. So, make sure highlighting is supported and enabled in your editor, whatever your application is.</p> <p>The first orange part in our code is immediately at line three. However the string contains only a newline character. This should be obvious enough in my opinion, so we can move on.</p> <p>When it comes to deciding what to extract and what to keep unchanged, there are few thumb-ups, but at the end it is your professional opinion that must prevail. Based on it, you will have to decide what to do with each piece of code you analyze.</p> <pre class="brush: php">for ($i = 0; $i < 50; $i++) { array_push($this->popQuestions, "Pop Question " . $i); array_push($this->scienceQuestions, ("Science Question " . $i)); array_push($this->sportsQuestions, ("Sports Question " . $i)); array_push($this->rockQuestions, $this->createRockQuestion($i)); } } function createRockQuestion($index) { return "Rock Question " . $index; }</pre> <p>So let's analyze lines 32 to 42, the snippet you can see above. For pop, science, and sports questions, there is just a simple concatenation. However, the action to compose the string for a rock question is extracted into a method. In your opinion, are these concatenations and strings clear enough so that we can keep all of them inside our for loop? Or, do you think extracting all strings into their methods would justify the existence of those methods? If so, how would you name those methods?</p> <h3>Update Golden Master and the Tests</h3> <p>Regardless of the answer, we will need to modify the code. It is time to put our <a href="">Golden Master</a> to work and write our test that actually runs and compares our code with the existing content.</p> <pre class="brush: php">class GoldenMasterTest extends PHPUnit_Framework_TestCase { private $gmPath; function setUp() { $this->gmPath = __DIR__ . '/gm.txt'; } function testGenerateOutput() { $times = 20000; $this->generateMany($times, $this->gmPath); } function testOutputMatchesGoldenMaster() { $times = 20000; $actualPath = '/tmp/actual.txt'; $this->generateMany($times, $actualPath); $file_content_gm = file_get_contents($this->gmPath); $file_content_actual = file_get_contents($actualPath); $this->assertTrue($file_content_gm == $file_content_actual); } private function generateMany($times, $fileName) {...} private function generateOutput($seed) {...} }</pre> <p>We created another test to compare the outputs, made sure <code>testGenerateOutput()</code> only generates the output once and does nothing else. We also moved the golden master output file <code>"gm.txt"</code> into the current directory because <code>"/tmp"</code> may be cleared when the system reboots. For our actual results, we can still use it. On most UNIX like systems <code>"/tmp"</code> is mounted into the RAM so it is much faster than the file system. If you did well, the tests should pass without a problem.</p><figure class="post_image"><img alt="" src=""></figure> <p>It is very important to remember to mark our generator test as "skipped" for future changes. If you feel more comfortable with commenting or even deleting it altogether, please do so. It is important that our <a href="">Golden Master</a> will not change when we change our code. It was generated once and we do not want to modify it, ever, so that we can be sure our newly generated code always compares to the original. If you feel more comfortable doing a backup of it, please proceed to do so.</p> <pre class="brush: php">function testGenerateOutput() { $this->markTestSkipped(); $times = 20000; $this->generateMany($times, $this->gmPath); }</pre> <p>I will just mark the test as skipped. This will put our test result to <code>"yellow"</code>, meaning all tests are passing but some are skipped or marked as incomplete.</p><figure class="post_image"><img alt="" src=""></figure> <h3>Making Our First Change</h3> <p>With tests in place, we can start changing code. In my professional opinion, all the strings can be kept inside the <code>for</code> loop. We will take the code from the <code>createRockQuestion()</code> method, move it inside the the <code>for</code> loop, and delete the method altogether. This refactoring is called <em>Inline Method</em>.</p> <p>"Put the method's body into the body of its callers and remove the method." ~ Martin Fowler</p> <p>There are a specific set of steps to do this type of refactoring, as defined by Marting Fowler in <a href="">Refactoring: Improving the Design of Existing Code</a>: </p> <ul> <li>Check that the method is not polymorphic.</li> <li>Find all calls to the method.</li> <li>Replace each call with the method body.</li> <li>Compile and test.</li> <li>Remove the method definition.</li> </ul> <p>We don't have subclasses extending <code>Game</code>, so the first step validates.</p><figure class="post_image"><img alt="" src=""></figure> <p>There is only a single use of our method, inside the <code>for</code> loop.</p> <pre class="brush: php">function __construct() { $this->players = array(); $this->places = array(0); $this->purses = array(0); $this->inPenaltyBox = array(0); $this->popQuestions = array(); $this->scienceQuestions = array(); $this->sportsQuestions = array(); $this->rockQuestions = array(); for ($i = 0; $i < 50; $i++) { array_push($this->popQuestions, "Pop Question " . $i); array_push($this->scienceQuestions, ("Science Question " . $i)); array_push($this->sportsQuestions, ("Sports Question " . $i)); array_push($this->rockQuestions, "Rock Question " . $i); } } function createRockQuestion($index) { return "Rock Question " . $index; }</pre> <p>We put the code from <code>createRockQuestion()</code> into the <code>for</code> loop in the constructor. We still have our old code. It is now time to run our test.</p> <p>Our tests are passing. We can delete our <code>createRockQuestion()</code> method.</p> <pre class="brush: php">function __construct() { // ... // for ($i = 0; $i < 50; $i++) { array_push($this->popQuestions, "Pop Question " . $i); array_push($this->scienceQuestions, ("Science Question " . $i)); array_push($this->sportsQuestions, ("Sports Question " . $i)); array_push($this->rockQuestions, "Rock Question " . $i); } } function isPlayable() { return ($this->howManyPlayers() >= 2); }</pre> <p>Finally we should run our tests again. If we missed a call to a method, they will fail.</p> <p>They should pass again. Congrats! We are done with our first refactoring.</p> <h3>Other Strings to Consider</h3> <p>Strings in the methods <code>add()</code> and roll() are only used to output them using the <code>echoln()</code> method. <code>askQuestions()</code> compares strings to categories. This seems acceptable also. <code>currentCategory()</code> on the other hand returns strings based on a number. In this method, there are a lot of duplicated strings. Changing any category, except Rock would require changing its name in three places, only in this method.</p> <pre class="brush: php">function currentCategory() { if ($this->places[$this->currentPlayer] == 0) { return "Pop"; } if ($this->places[$this->currentPlayer] == 4) { return "Pop"; } if ($this->places[$this->currentPlayer] == 8) { return "Pop"; } if ($this->places[$this->currentPlayer] == 1) { return "Science"; } if ($this->places[$this->currentPlayer] == 5) { return "Science"; } if ($this->places[$this->currentPlayer] == 9) { return "Science"; } if ($this->places[$this->currentPlayer] == 2) { return "Sports"; } if ($this->places[$this->currentPlayer] == 6) { return "Sports"; } if ($this->places[$this->currentPlayer] == 10) { return "Sports"; } return "Rock"; }</pre> <p>I think we can do better. We can use a refactoring method called <em>Introduce Local Variable</em> and eliminate the duplication. Follow these guidelines:</p> <ul> <li>Add a variable with the desired value.</li> <li>Find all uses of the value.</li> <li>Replace all uses with the variable.</li> </ul> <pre class="brush: php">function currentCategory() { $include_once __DIR__ . '/Game.php'; $notAWinner; $aGame = new Game(); $aGame->add("Chet"); $aGame->add("Pat"); $aGame->add("Sue"); do { $aGame->roll(rand(0, 5) + 1); if (rand(0, 9) == 7) { $notAWinner = $aGame->wrongAnswer(); } else { $notAWinner = $aGame->wasCorrectlyAnswered(); } } while ($notAWinner);</pre> <p>We'll start with <code>GameRunner.php</code> this time and our first focus is the <code>roll()</code> method that gets some random numbers. The previous author did not care to give those numbers a meaning. Can we? If we analyze the code:</p> <pre class="brush: php">rand(0, 5) + 1</pre> <p>It will return a number between one and six. The random part returns a number between zero and five to which we always add one. So it is surely between one and six. Now we need to consider the context of our application. We are developing a trivia game. We know there is some kind of board on which our players must move. And to do so, we need to roll the dice. A die has six faces and it can produce numbers between one and six. That seems like a reasonable deduction.</p> <pre class="brush: php">$dice = rand(0, 5) + 1; $aGame->roll($dice);</pre> <p>Isn't that nice? We used the Introduce Local Variable refactoring concept again. We named our new variable <code>$dice</code> and it represents the random number generated between one and six. This also made our next statement sound really natural: Game, roll dice.</p> <p>Did you run your tests? I didn't mention it, but we need to run them as frequently as possible. If you haven't, this would be a good time to run them. And they should pass.</p> <p>So, this was a case of nothing more than just exchanging a number with a variable. We took a whole expression that represented a number and extracted it into a variable. This can be technically considered a Magic Constant case, but not a pure case. What about our next random expression?</p> <pre class="brush: php">if (rand(0, 9) == 7)</pre> <p>This is more tricky. What are zero, nine and seven in that expression? Maybe we can name them. At first glance, I have no good ideas for zero and nine, so let's try seven. If the number returned by our random function is equal to seven, we will enter the first branch of the <code>if</code> statement which produces a wrong answer. So maybe our seven could be named <code>$wrongAnswerId</code>.</p> <pre class="brush: php">$wrongAnswerId = 7; if (rand(0, 9) == $wrongAnswerId) { $notAWinner = $aGame->wrongAnswer(); } else { $notAWinner = $aGame->wasCorrectlyAnswered(); }</pre> <p>Our tests are still passing and the code is somewhat more expressive. Now that we managed to name our number seven, it puts the conditional into a different context. We can think of some decent names for zero and nine also. They are just parameters to <code>rand()</code>, so the variables will probably be named min-something and max-something.</p> <pre class="brush: php">$minAnswerId = 0; $maxAnswerId = 9; $wrongAnswerId = 7; if (rand($minAnswerId, $maxAnswerId) == $wrongAnswerId) { $notAWinner = $aGame->wrongAnswer(); } else { $notAWinner = $aGame->wasCorrectlyAnswered(); }</pre> <p>Now that is expressive. We have a minimum answer ID, a maximum one and another for the wrong answer. Mystery solved.</p> <pre class="brush: php">do { $dice = rand(0, 5) + 1; $aGame->roll($dice); $minAnswerId = 0; $maxAnswerId = 9; $wrongAnswerId = 7; if (rand($minAnswerId, $maxAnswerId) == $wrongAnswerId) { $notAWinner = $aGame->wrongAnswer(); } else { $notAWinner = $aGame->wasCorrectlyAnswered(); } } while ($notAWinner);</pre> <p>But notice that all the code is inside a <code>do-while</code> loop. Do we need to re-assign the answer ID variables each time? I think not. Let's try to move them out of the loop and see if our tests are passing.</p> <pre class="brush: php">$minAnswerId = 0; $maxAnswerId = 9; $wrongAnswerId = 7; do { $dice = rand(0, 5) + 1; $aGame->roll($dice); if (rand($minAnswerId, $maxAnswerId) == $wrongAnswerId) { $notAWinner = $aGame->wrongAnswer(); } else { $notAWinner = $aGame->wasCorrectlyAnswered(); } } while ($notAWinner);</pre> <p>Yes. The tests pass like this as well.</p> <p>It's time to switch to <code>Game.php</code> and look for Magic Constants there also. If you have code highlighting, you surely have constants highlighted in some bright color. Mine are blue and they are pretty easy to spot.</p><figure class="post_image"><img alt="" src=""></figure> <p>Finding the magic constant 50 in that <code>for</code> loop was quite easy. And if we look at what the code does, we can discover that inside the <code>for</code> loop, elements are pushed to several arrays. So we have some kind of lists, each with 50 elements. Each list represents a question category and the variables are actually class fields defined above as arrays. </p> <pre class="brush: php">$this->popQuestions = array(); $this->scienceQuestions = array(); $this->sportsQuestions = array(); $this->rockQuestions = array();</pre> <p>So, what can 50 represent? I bet you already have some ideas. Naming is one of the most difficult tasks in programming, if you have more than one idea and you feel uncertain which one to choose, don't be ashamed. I also have various names in my head and I am evaluating possibilities for choosing the best one, even while writing this paragraph. I think we can go with a conservative name for 50. Something along the lines of<code>$questionsInEachCategory</code> or <code>$categorySize</code> or something similar.</p> <pre class="brush: php">$categorySize = 50; for ($i = 0; $i < $categorySize; $i++) { array_push($this->popQuestions, "Pop Question " . $i); array_push($this->scienceQuestions, ("Science Question " . $i)); array_push($this->sportsQuestions, ("Sports Question " . $i)); array_push($this->rockQuestions, "Rock Question " . $i); }</pre> <p>That looks decent. We can keep it. And the tests are of course are passing.</p> <pre class="brush: php">function isPlayable() { return ($this->howManyPlayers() >= 2); }</pre> <p>What is two? I am sure at this point the answer is clear to you. That is easy:</p> <pre class="brush: php">function isPlayable() { $minimumNumberOfPlayers = 2; return ($this->howManyPlayers() >= $minimumNumberOfPlayers); }</pre> <p>Do you agree? If you have a better idea, feel free to comment below. And your tests? Are they still passing?</p> <p>Now, in the <code>roll()</code> method we have some numbers also: two, zero, 11 and 12.</p> <pre class="brush: php">if ($roll % 2 != 0)</pre> <p>That is pretty clear. We will extract that expression into a method, but not in this tutorial. We are still in the phase of understanding and hunting for magic constants and strings. So what about 11 and 12? They are buried inside the third level of <code>if</code> statements. It is quite difficult to understand what they stand for. Maybe if we look at the lines around them.</p> <pre class="brush: php">if ($this->places[$this->currentPlayer] > 11) { $this->places[$this->currentPlayer] = $this->places[$this->currentPlayer] - 12; }</pre> <p>If the current player's place or position is greater than 11, then its position will be reduced to the current one minus 12. This sounds like a case of when a player reaches the end of the board or play field and it is repositioned in its initial position. Probably position zero. Or, if our game board is circular, going over the last marked position will put the player into the relative first position. So 11 could be the board size. </p> <pre class="brush: php">$boardSize = 11; if ($this->inPenaltyBox[$this->currentPlayer]) { if ($roll % 2 != 0) { // ... // if ($this->places[$this->currentPlayer] > $boardSize) { $this->places[$this->currentPlayer] = $this->places[$this->currentPlayer] - 12; } // ... // } else { // ... // } } else { // ... // if ($this->places[$this->currentPlayer] > $boardSize) { $this->places[$this->currentPlayer] = $this->places[$this->currentPlayer] - 12; } // ... // }</pre> <p>Don't forget to replace 11 in both places inside the method. This will force us to move the variable assignment outside of the <code>if</code> statements, right at the first indentation level.</p> <p>But if 11 is the board's size, what is 12? We subtract 12 from the player's current position, not 11. And why don't we just set the position to zero instead of subtracting? Because that would make our tests fail. Our previous guess that the player will end up in position zero after the code inside the <code>if</code> statement is run, was wrong. Let's say a player is in position ten and rolls a four. 14 is greater than 11, so the subtraction will happen. The player will end up in position <code>10+4-12=2</code>.</p> <p>This drives us toward another possible naming for 11 and 12. I think it is more appropriate to call 12 <code>$boardSize</code>. But what does that leave us for 11? Maybe <code>$lastPositionOnTheBoard</code>? A little bit long, but at least it tells us the truth about the magic constant.</p> <pre class="brush: php">$lastPositionOnTheBoard = 11; $boardSize = 12; if ($this->inPenaltyBox[$this->currentPlayer]) { if ($roll % 2 != 0) { // ... // if ($this->places[$this->currentPlayer] > $lastPositionOnTheBoard) { $this->places[$this->currentPlayer] = $this->places[$this->currentPlayer] - $boardSize; } // ... // } else { // ... // } } else { // ... // if ($this->places[$this->currentPlayer] > $lastPositionOnTheBoard) { $this->places[$this->currentPlayer] = $this->places[$this->currentPlayer] - $boardSize; } // ... // }</pre> <p>I know, I know! There is some code duplication there. It is quite obvious, especially with the rest of the code hidden. But please remember that we were after magic constants. There will be a time for duplicate code also, but not right now.</p> <h2>Final Thoughts</h2> <p>I left one last magic constant in the code. Can you spot it? If you look at the final code, it will be replaced, but of course that would be cheating. Good luck finding it-02T15:00:04.876Z 2014-04-02T15:00:04.876Z Patkos Csaba tag:code.tutsplus.com,2005:PostPresenter/cms-20475 Using Polymer to Create Web Components <p><b><i>Editors Note:</i></b> <i>This article was updated to remove references to deprecated components specifically polymer-ajax which has since been replaced by core-ajax. Thanks to </i><a target="_self" href=""><i>Rob Dodson</i></a><i>, developer advocate at Google, for the feedback.</i><br></p><p?</p> <p>Web Components aim to solve some of these complexities by providing a unified way to create new elements that encompass rich functionality without the need for all the extra libraries. Web components are comprised of four different specifications (<a href="">Custom Elements</a>, <a target="_self" href="">Templates</a>, <a href="">Shadow DOM</a> and <a href="">HTML imports</a>) which are being fleshed out in the W3C. </p> <p>To bridge the gap and give developers access to this rich functionality now, Google has created the <a href="">Polymer</a> library which serves as a set of polyfills to bring the promise of Web Components to you today. Let's dive a little deeper into.</p> <h2>What Is Polymer</h2> <p: </p> <ul> <li>Encapsulating much of the complex code and structure</li> <li>Allowing developers to use a simple-to-use tag style naming convention</li> <li>Providing a suite of predefined UI elements to leverage and extend</li> </ul> <p>But the important thing to remember, is that the framework itself is developed based on the direction of the individual specifications being vetted by the W3C, thus providing a foundation that should evolve with the direction of the main standards body.</p> <p>What this library can do, is allow us to create reusable components that work as true DOM elements while helping to minimize our reliance on JavaScript to do complex DOM manipulation to render rich UI results. </p> <p>Here's a quick example from the Polymer site. Say I wanted to render a working clock on my page. That would typically entail some heavy duty JavaScript code to do but by using Polymer, I can simply use the following syntax:</p> <pre class="brush: html"><polymer-ui-clock></polymer-ui-clock></pre> <p>This looks like the HTML tag syntax we've all grown up with and is far easier to implement, read and maintain than some complex JavaScript code. And the end result looks like this: </p><figure class="post_image"><img src="" alt=""></figure><p>And since it's a normal element in the DOM, you can style it as well using CSS like this:</p> <pre class="brush: css"> polymer-ui-clock { width: 320px; height: 320px; display: inline-block; background: url("../assets/glass.png") no-repeat; background-size: cover; border: 4px solid rgba(32, 32, 32, 0.3); } </pre> <p>It's certainly not the prettiest clock, but that's not the point. The fact is that you can customize the component to your liking and then reuse it via an easier and more maintainable syntax.</p> <h2>Installing Polymer</h2> <p>There are three ways to install and use Polymer:</p> <ul> <li>Use the Bower package manager (preferred)</li> <li>Use the libraries hosted on CloudFare's <a href="">cdnjs</a></li> <li>Install from Git</li> </ul> <p>Of the three, the easiest and recommended way is to use <a href="">Bower</a> because not only is it incredibly easy to do but Bower also manages any dependencies that Polymer might have. This means that if you choose to install a specific UI element which has a dependency on another one, Bower can handle that for you.</p> <p>Bower is installed as a Node Packaged Module, so you'll need to have <a href="">Node.js</a> installed. From the command line, type in the following:</p> <pre class="brush: bash">npm install -g bower </pre> <p>This should pull Bower from the npm registry and install it so it's globally available to you. From there, subsequent Bower-based installs take the following form:</p> <pre class="brush: bash">bower install </pre> <p>At a bare minimum, you're going to want to install Polymer's platform and core components since they provide the foundation for you to create and run your customer elements.</p><pre class="brush: bash">bower install --save Polymer/platform bower install --save Polymer/polymer</pre> <p>You can shortcut this by typing in:</p> <pre class="brush: bash">bower install --save Polymer/platform Polymer/polymer </pre> <p>Polymer also comes with a rich, predefined set of elements that you can begin taking advantage of immediately. They consist of <a target="_self" href="">UI and non-UI</a> based elements that provide functionality such as:</p> <ul> <li>Animation</li> <li>Accordions</li> <li>Grid layout</li> <li>Ajax capabilities</li> <li>Menus</li> <li>Tabs</li> </ul> <p>And that's only scraping the surface. There's a lot already in there with full source code available to serve as a learning tool, as well as allow you to customize the capabilities to your needs.</p> <p>You have a choice in how to install these components. You can install everything or only those you want to use. To install everything, you type in:</p> <pre class="brush: bash">bower install Polymer/core-elements bower install Polymer/polymer-ui-elements</pre> <p>This is the kitchen sink approach and when you're starting out learning Polymer, it's probably easiest just to do that, to help you get a feel for what's available.</p> <p>Once you're more familiar with the framework, you can cherry-pick the individual components you'd like to use and install them like this:</p> <pre class="brush: bash">bower install Polymer/polymer-ui-accordion </pre> <p>This is the beauty of using Bower. Every component comes with a <code>bower.json</code> configuration file that outlines its dependencies. So if you were installing the <code>accordion</code> component, looking at the config, we can see that it has dependencies on the main <code>polymer</code> component as well as the <code>selector</code> and <code>collapsible</code> components.</p> <pre class="brush: javascript">{ "name": "polymer-ui-accordion", "private": true, "dependencies": { "polymer": "Polymer/polymer#0.2.0", "polymer-selector": "Polymer/polymer-selector#0.2.0", "polymer-ui-collapsible": "Polymer/polymer-ui-collapsible#0.2.0" }, "version": "0.2.0" } </pre> <p>The key thing is that you don't have to worry about that because Bower manages that for you. This is why it's the preferred tool for installing Polymer.</p> <p>Installing via Bower will create a folder called <code>bower_components</code> in your project folder housing all of the stuff Polymer needs.</p> <h2>Making a New Polymer Element</h2> <p>The Polymer site pretty much nails the description of custom elements:</p> <p>“Custom Elements are the core building blocks of Polymer-based applications. You create applications by assembling custom elements together, either ones provided by Polymer, ones you create yourself, or third-party elements.”</p> <p>Polymer gives us the ability to create our own custom elements from scratch and even reuse other elements to extend our custom ones. This is done by first creating a template of the custom element. For all intents, this template is a combination of HTML, CSS and JavaScript and includes the functionality that will be available when you use the element. It's based off the <a href="">WhatWG HTML Templates specification</a> which is meant to provide native support for client-side templating.</p> <p>Let's look at this simple example of a Polymer template:</p> <pre class="brush: html"><link rel="import" href="../bower_components/polymer/polymer.html"> <polymer-element <template> > </template> </polymer-element></pre> <p>This Element allows you to easily add Lorem Ipsum text into your code by simply using the following tag:</p> <pre class="brush: html"><lorem-element></lorem-element></pre> <p>The first thing that needs to be included is Polymer core, which is the main API that allows you to define the Custom Elements:</p> <pre class="brush: html"><link rel="import" href="../bower_components/polymer/polymer.html"></pre> <p>The next step is defining the name of the new element using Polymer's <code>polymer-element</code> directive: </p> <pre class="brush: html"><polymer-element</pre> <p>In this case, I've named my new element <code>lorem-element</code>. The name is a required attribute and it must contain a dash (“-”). </p> <p>From there we use the <code>template</code> directive to wrap the main body tags and code that will make up our new element. For this simple example, I grab Lorem Ipsum text and wrapped it with paragraph tags.</p> <p>That's it! My custom element is done and I can now use it. </p> <h2>Using Your New Polymer Element</h2> <p>Keep in mind that this component will be imported into other pages in your web app that may want to leverage it. This is possible because of Polymer's implementation of the HTML Imports specification that allows you to include and reuse HTML documents in other HTML documents.</p> <p>First, you need to include <code>platform.js</code> which provides the polyfill that mimicks the native APIs:</p> <pre class="brush: html"><script src="bower_components/platform/platform.js"></script></pre> <p>Next, we need to import our custom element into our web page:</p> <pre class="brush: html"><link rel="import" href="lorem-element.html"></pre> <p>Once you've done this, your new custom element is now available allowing you to do something like this:</p> <pre class="brush: html"><div><lorem-element></lorem-element></div></pre> <p>You also have the ability to fully style the element as well: </p> <pre class="brush: html"><style> div { width: 300px;} lorem-element { font: bold 16px cursive;} </style></pre> <p>This is a pretty basic example. Let's take it a step further.</p> <h2>Adding More Functionality to Your Element</h2> <p>If you remember, I mentioned how you can leverage existing elements to enhance your custom one. Let's look at an example of this.</p> <p>Suppose I wanted to have an element that went out to Reddit and grabbed data from one of the subreddits. I could take advantage of Polymer's existing Ajax component by including that in my custom element like this:</p> <pre class="brush: html"><link rel="import" href="../bower_components/polymer/polymer.html"> <link rel="import" href="../bower_components/core-ajax/core-ajax.html"> <polymer-element <template> <core-ajax</core-ajax> <p>{{resp.data.public_description}}</p> </template> </polymer-element> </pre> <p:</p> <p>“Things that make you go AWW! Like puppies. And bunnies... and so on... A place for really cute pictures, videos and stories!”</p> <p>The response is returned and Polymer establishes a two-way data binding that allows me to be able to use the data by wrapping it in double curly braces like this <code>{{resp.data.public_description}}</code>.</p> <p>This is cool but in most cases, we're not going to hardcode a URL for a specific resource. Let's expand this further by adding attributes to our custom element. Doing this is incredibly simple. First, you need to update the <code>polymer-element</code> directive to reflect the attributes you want for your custom element:</p> <pre class="brush: html"><polymer-element</pre> <p>In this case, I want to be able to pass a subreddit to my element and have it pull back data based on that. I can now change the call to <code>polymer-ajax</code> like this:</p> <pre class="brush: html"><core-ajax</core-ajax></pre> <p>Notice how I'm using Polymer's data binding capabilities to dynamically build the URL based on the attribute value of <code>{{subreddit}}</code>. Now, I can update how I reference my custom element to pass in the subreddit that I want:</p> <pre class="brush: html"><reddit-element</reddit-element></pre> <p>The last thing I want to do is ensure there's a default value for my attribute so my code doesn't blow up. I do this by adding the following into my element template:</p> <pre class="brush: html"> <script> Polymer('reddit-element', { subreddit: "aww" }); </script></pre> <p>This ensures that I'll always have a default value for my element's public attribute. Here's how the final code looks like:</p> <pre class="brush: html">> </pre> <p>And there's quite a bit more stuff you can do including adding custom callback handlers, managing events, setting up Mutation Observers to process changes to the DOM and much more.</p> <h2>The Future Is Here</h2> <p-31T15:00:02.655Z 2014-03-31T15:00:02.655Z Rey Bango tag:code.tutsplus.com,2005:PostPresenter/cms-20442 Test Code Coverage: From Myth to Reality <p>There.</p> <p>But times have changed..</p> <p>Automated testing and test driven development (TDD) are some of the essential techniques Agile provided to us programmers. And a tool that comes with those methodologies is used to produce test code coverage, which is the topic of this article.</p> <h2>Definition</h2> <p>"In computer science, code coverage is a measure used to describe the degree to which the source code of a program is tested by a particular test suite." ~ Wikipedia </p> <p.</p> <p>Information can be presented in various ways, from simple percentages to nice graphics or even real-time highlighting in your favorite IDE.</p> <h2>Let's Check It in Action</h2> <p>We will use PHP as the language to exemplify our code. Additionally, we will need PHPUnit and XDebug to test our code and gather coverage data.</p> <h3>The Source Code</h3> <p>Here is the source code we will use. You can also find it in the attached archive.</p> <pre class="brush: php"; } }</pre> <p>The above code contains a simple function that wraps text to a specified number of characters, per line.</p> <h3>The Test Code</h3> <p>We wrote this code using <a href="">Test Driven Development (TDD)</a> and we have 100% code coverage for it. This means that by running our test, we exercise each and every line of the source code.</p> <pre class="brush: php")); } }</pre> <h3>Running the Tests in CLI With Text Only Coverage</h3> <p.</p> <p>Let's open a console and change directories in to your <code>test</code> folder. Then run <code>phpunit</code> with an option to generate coverage data as plain text.</p> <pre class="brush: bash">phpunit --coverage-text=./coverage.txt ./WordWrapTest.php</pre> <p>This should work out of the box on most systems if XDebug is installed, however in some cases, you may encounter an error related to time zones.</p> <pre class="brush: bash" phar:///usr/share/php/phpunit/phpunit.phar/ PHP_CodeCoverage-1.2.10/PHP/CodeCoverage/Report/Text.php on line 124 </pre> <p>This can be easily fixed by specifying the suggested setting in your <code>php.ini</code> file. You can find the way to specify your timezone in <a href="">this list</a>. I am from Romania, so I will use the following setting:</p> <pre class="brush: bash">date.timezone = Europe/Bucharest</pre> <p>Now, if you run the <code>phpunit</code> command again, you should see no error messages. Instead, the test results will be shown.</p> <pre class="brush: bash">PHPUnit 3.7.20 by Sebastian Bergmann. .. Time: 0 seconds, Memory: 5.00Mb OK (2 tests, 7 assertions) </pre> <p>And the coverage data will be in the specified text file.</p> <pre class="brush: bash">$ cat ./coverage.txt Code Coverage Report 2014-03-02 13:48:11 Summary: Classes: 100.00% (1/1) Methods: 100.00% (1/1) Lines: 2.68% (14/522) WordWrap Methods: 100.00% ( 1/ 1) Lines: 100.00% ( 7/ 7) </pre> <p>Let's analyze this a little bit.</p> <ul> <li><em>Classes</em>: refers to how many classes were tested and how many of them were covered. <code>WordWrap</code> is our only class.</li> <li><em>Methods</em>: same as with classes.

Each section has its own methods and line details. </li> </ul> <p>Based on these observations, we can conclude that our code is 100% covered by tests. Exactly as we expected before analyzing the coverage data.</p> <h3>Generating HTML Coverage Output</h3> <p>By just changing a simple parameter for PHPUnit, we can generate nice HTML output.</p> <pre class="brush: bash">$ mkdir ./coverage $ phpunit --coverage-html ./coverage ./WordWrapTest.php </pre> <p>If you check your <code>./coverage</code> directory, you will find a lot of files there. I won't paste the list here because it is quite extensive. Instead, I will show you how it looks in a web browser.</p><figure class="post_image"><img alt="" src=""></figure><p>This is the equivalent of the summary section from the text version above. We can zoom in by following the proposed links and see more details.</p><figure class="post_image"><img alt="" src=""></figure><h3>Coverage Inside Our IDE</h3> <p>The previous examples were interesting and they are quite useful, <em>if</em> your code is built on some remote server to which you have only SHH or web access to. But wouldn't it be nice to have all this info, live in your IDE?</p> <p>If you use PHPStorm, everything is within the distance of a single click! Select to run your tests with coverage and all the info will just simply show up, magically.</p><figure class="post_image"><img alt="" src=""></figure><p>The coverage information will be present in your IDE, in several ways and in several places:</p><figure class="post_image"><img alt="" src=""></figure> <ol> <li>Test coverage percentage will be shown near each directory and file.</li> <li.</li> <li>On the right side there will be file browsers where you can quickly browse and sort files by coverage.</li> <li>In the test output, you will see a line of text announcing to you that code coverage was generated.</li> </ol> <h2>The Myths About Code Coverage</h2> <p.</p> <p.</p> <p?</p> <pre class="brush: php">function testItCanWrap() { $w = new WordWrap(); $this->assertEquals("a b\nc", $w->wrap('a b c', 3)); $this->assertEquals("a\nbc\nd", $w->wrap('a bc d', 3)); }</pre> <p>That's it. Two assertions and full coverage. This is not what we want. This test is so far from descriptive and complete, that it is ridiculous.</p> <h2>The Reality About Code Coverage</h2> <p>Code coverage is a status indicator, not a unit to measure performance or correctness.</p> <p>Code coverage is for programmers, not for managers. It is a way to spot problems in our code. A way to find old, untested classes. A way to find paths not exercised by the tests that could lead to problems.</p> <p>On real projects, code coverage will always be under 100%. Achieving perfect coverage is not possible, or if it is, it's rarely a must. However, to have 98% of coverage you must target 100%. Having anything else as your target is non-sense.</p> <p>Here is the code coverage on Syneto's StorageOS configuration application.</p><figure class="post_image"><img alt="" src=""></figure><p>The total is only about 35%, but the results need interpretation. Most of the modules are in the green, with more than 70% coverage. However there is a single folder, <code>Vmware</code>,.<br></p> <h2>Final Thoughts</h2> <p-28T15:00:12.697Z 2014-03-28T15:00:12.697Z Patkos Csaba tag:code.tutsplus.com,2005:PostPresenter/cms-20405 Easily Deploy Redis Backed Web Apps With Docker <p>The people who make <a href="">Docker</a> like to describe it using a metaphor to a pretty ancient piece of technology: the shipping container. </p> <p. </p> <p>Docker tries to take this same level of convenience and bring it to the server world. It's the natural extension of tools like <a href="">Vagrant</a>. </p> <h2>Introduction</h2> <p. </p> <p>We'll just be deploying a toy sample app, but the steps to deploy your own real apps would be very similar. </p> <p. </p> <h2>Installing Docker</h2> <p>The first step is to install Docker itself. Docker is under very quick development, so the easiest way to install it often changes quite quickly. Check out Docker's <a href="">getting started section</a> if you want to check out the cutting edge. </p> <p>Otherwise, follow the steps below and we'll set up a Vagrant virtual machine based install of Docker that will work on any of the major operating systems. First head over to <a href="">Vagrant's website</a> and install the latest Vagrant and VirtualBox for your OS. </p> <p>Once Vagrant is installed, make a new folder, open a command prompt there and do the following:</p> <pre class="brush: bash">vagrant init hashicorp/precise64 (... wait a while ...) vagrant up vagrant ssh </pre> <p>Vagrant just took care of creating a virtual machine running Ubuntu 12.04 for you and you're now SSH'd into its prompt. We can now follow Docker's Ubuntu installation instructions. Check <a href="">the website</a> in case there have been any changes since this was written, but most likely, you can directly paste the following commands into the terminal:</p> <pre class="brush: bash"># install the backported kernel sudo apt-get update sudo apt-get install linux-image-generic-lts-raring linux-headers-generic-lts-raring # reboot sudo reboot </pre> <p>You'll get dropped back to your local machine's prompt when the VM reboots, so wait a few moments and do another:</p> <pre class="brush: bash">vagrant ssh </pre> <p>... to SSH back into your VM. Now that Docker's prerequisites have been installed successfully, we need to go ahead and install Docker itself. Paste in the following command:</p> <pre class="brush: bash">curl -s | sudo sh </pre> <p>... which will grab a simple Docker install script from Docker's site and run it. Docker should now be installed successfully, so let's start playing with it. </p> <h2>Getting Started With Docker</h2> <p>Once <code>apt-get</code> has finished its magic, do the following:</p> <pre class="brush: bash">sudo Docker run -i -t ubuntu /bin/bash </pre> <p>... <code>root</code> and <code>#</code> sign in the prompt. You're running as the root user in a new virtual environment. If you issue a <code>users</code> command, you'll see that your other users are no longer present. </p> <p>It's worth taking a minute to explain what the <code>docker</code> command you just typed did and how this magic happened.</p> <h2>The <code>run</code> Command</h2> <p>The Docker utility seems to have taken a lot of inspiration from <code>git</code>'s command line interface and as a result, it makes use of subcommands. In this case, we ran the <code>run</code> subcommand. The <code>run</code> command requires two arguments: an image and a command. </p> <p>It's also smart, so if (as in this case) you don't have that image installed, it will query the central Docker repository and download one for you. Here we told it to run an <code>ubuntu</code> image and informed Docker that it should start <code>/bin/bash</code> inside that image. The <code>-t</code> and <code>-i</code> <code>chroot</code> command than to more traditional virtualization tools like VMWare or VirtualBox. </p> <p>There are some other key differences from standard virtualization tools. Let's do a quick experiment and create a file and print out the contents of it:</p> <pre class="brush: bash">echo An experiment > experiment.txt </pre> <p>Now when you do:</p> <pre class="brush: bash">cat experiment.txt </pre> <p>It will happily print out:</p> <pre class="brush: bash">An experiment </pre> <p>So far so good, our silly experiment is working exactly as expected. Let's exit Docker and get back to our host machine's command prompt:</p> <pre class="brush: bash">exit </pre> <p>If you restart Docker with the same command you used before: </p> <pre class="brush: bash">sudo Docker run -i -t ubuntu /bin/bash </pre> <p>... you'll notice that things are no longer behaving quite the way you would expect. If you try to cat the file we created last time, you now get an error message:</p> <pre class="brush: bash">root@e97acdf4160c:/# cat experiment.txt cat: experiment.txt: No such file or directory </pre> <p>So what's going on? Changes to Docker images don't persist by default. To save your changes to a Docker image, you have to <code>commit</code> them, <code>git</code> style. This might take a little getting used to, but it's quite powerful because it means you can also "branch" them <code>git</code> style (more on that later). </p> <h2>Saving New Images</h2> <p>For now, let's do something a little more useful. Let's install <code>python</code>, <code>redis</code> and a few other utilities that we'll use to run our demo app shortly. Afterwards, we'll <code>commit</code> to persist our changes. Start a copy of Docker up on the latest Ubuntu image:</p> <pre class="brush: bash">docker -t -i ubuntu /bin/bash </pre> <p>The Ubuntu base image may not include Python, so check if you've got a copy by typing <code>python</code> at the prompt. If you get an error message, then let's install it:</p> <pre class="brush: bash">apt-get update apt-get install python </pre> <p>So far, so good. It's possible that later we'll want to make other projects that make use of Python, so let's go ahead and save these changes. Open up another command prompt (if you're using the Vagrant install recommended above, you'll have to <code>vagrant ssh</code> again from a separate prompt) and do the following:</p> <pre class="brush: bash">docker ps </pre> <p>You'll get a list like below, of all the Docker containers that are currently running:</p> <pre class="brush: plain">ID IMAGE COMMAND CREATED STATUS PORTS 54a11224dae6 ubuntu:12.04 /bin/bash 6 minutes ago Up 6 minutes </pre> <p>The number under the ID column is important: this is the ID of your container. These are unique, if you exit your container and run the same image again, you'll see a new number there. </p> <p>So now that we have Python installed, let's save our changes. To do this you use the <code>commit</code> command which takes two arguments: the container whose changes you want to store and the image name. The Docker convention is to use a userid followed by a <code>/</code> and the short name of the image. So in this case, let's call it <code>tuts/python</code>. Issue the following command to save your Python installation, making sure to substitute the ID for your container from the last step</p> <pre class="brush: bash">docker commit tuts/python </pre> <p>After a few seconds, it will return with a series of letters and numbers. This is the ID of the image you just saved. You can run this image whenever you want and refer to it either by this ID number or by the easier to remember <code>tuts/python</code> name we assigned to it. </p> <p>Let's run a copy of the image we just made:</p> <pre class="brush: bash">docker run -t -i tuts/python /bin/bash </pre> <p>At this point, you should have two terminal windows open running two separate Docker sessions.</p> <p>You'll notice now that if you type <code>python</code> in either one, you won't get an error message anymore. Try creating a file in the second window: </p> <pre class="brush: bash">touch /testfile </pre> <p>Now switch back to your original Docker window and try to look at the file:</p> <pre class="brush: bash">cat /testfile </pre> <p>You'll get an error message. This is because you're running an entirely different "virtual machine" based on the image you created with the <code>docker commit</code> command. Your file systems are entirely separate. </p> <p>If you open up yet another terminal (again, you'll have to run <code>vagrant ssh</code> if using Vagrant) and do the following:</p> <pre class="brush: bash">docker ps </pre> <p>... you'll see that <code>docker</code> now lists two running images, not just one. You can separately commit to each of those images. To continue with the <code>git</code> metaphor, you're now working with two branches and they are free to "diverge". </p> <p>Let's go ahead and close the last window we opened. If you run <code>docker ps</code> again, there will now only be one ID listed. But what if you want to get back to a previous container? If you type:</p> <pre class="brush: bash">docker ps -a </pre> <p>Docker will list out all previous containers as well. You can't run a container that has exited, but you can use previous container's IDs to commit new images. Running the new image will then effectively get you back to your previous container's state.</p> <p <code>redis</code>, and the Redis server itself. </p> <pre class="brush: bash">apt-get install python-pip redis-server pip install redis bottle </pre> <p>Once these finish, let's commit this image. From another terminal window, run the following command:</p> <pre class="brush: bash">docker ps </pre> <p>... and take a note of the ID and commit it under the name <code>tuts/pyredis</code>:</p> <pre class="brush: bash">docker commit tuts/pyredis </pre> <p>So we now have a Docker image that contains the necessary tools to run a small Python web app with Redis serving as a backend. If you have any future projects that will use the same stack, all you have to do to get them started is: <code>docker run -t -i tuts/pyredis /bin/bash</code> and commit once you've added your source code. </p> <p>Ok, so our backend is set up. Now to set up the app itself!</p> <h2>Getting Your Source App Into the Image</h2> <p <code>vagrant ssh</code> session) first:</p> <pre class="brush: bash">cd git clone pyredis </pre> <p>In your host machine's home directory you'll now have a <code>pyredis</code> folder which contains the Python script we'll be using. So, how do we go about copying this app into our Docker image? </p> <p>Well, Docker has a nice feature that lets you mount a local directory inside your container. Let's run another Docker image and mount the folder:</p> <pre class="brush: bash">docker run -v ~/pyredis:/tuts:rw -t -i tuts/pyredis /bin/bash </pre> <p>This is just like our <code>run</code> commands from before, with the addition of the <code>-v</code> parameter. </p> <p>In effect, this command lets you share a folder between Docker and your host machine. The <code>:</code>'s indicate the paths to share. In our case, we're sharing our <code>pyredis</code> folder, located at <code>~/pyredis</code> on our machine, and mounting it at <code>/tuts</code> inside the Docker image. The <code>rw</code> on the end is for 'read-write' and means that changes made on the Docker image will also show up on our machine. </p> <p>At your Docker prompt, you can now do:</p> <pre class="brush: bash">cd /tuts ls </pre> <p>... and see the contents of the <code>~/pyredis</code> folder on your machine.</p> <p>This share is temporary though, if you run this Docker image on another computer or re-run this image without the <code>-v</code> option, the image will no longer have access to it. Let's copy it to another location inside the actual Docker image:</p> <pre class="brush: bash">cp -R /tuts/ /pyredis </pre> <p>Since changes to Docker file systems are ephemeral by default, let's save this to the image by again doing <code>docker ps</code> to get our container ID and committing our changes:</p> <pre class="brush: bash">docker commit tuts/pyredis </pre> <p>You'll notice here we committed to the same image name we committed to last time, <code>tuts/pyredis</code>. Docker will update the image and it will keep a log of all your changes for you. Like <code>git</code>, if you mess up, you can go back to a good version simply by <code>docker run</code>'ing its ID. To see the history of an image, try the following:</p> <pre class="brush: bash">docker history tuts/pyredis </pre> <p>You'll see something like this:</p> <pre class="brush: plain">ID CREATED CREATED BY tuts/pyredis:latest 17 seconds ago /bin/bash 4c3712e7443c 25 hours ago /bin/bash ubuntu:12.10 6 months ago /bin/bash 27cf78414709 6 months ago </pre> <p>This is a history of all the commits we made in the process of creating the <code>tuts/pyredis</code> image, including those we committed to different names like <code>tuts/python</code>. If you want to go back to the commit right before we copied our <code>pyredis</code> app into <code>/pyredis</code> you could try (changing the IDs to match what yours shows):</p> <pre class="brush: bash">docker run -t -i 4c3712e7443c /bin/bash </pre> <p>... and you'll find there's no <code>/pyredis</code> directory. </p> <h2>Running the App</h2> <p>So now we have all the pieces in place. The next step is to actually run the app from inside its container. Since we're deploying a web app, we're also going to need to specify some way to access the app over the web. The <code>run</code> command has got you covered (again). Docker's run command supports a <code>-p</code> option that lets you specify how ports will be mapped. </p> <p>If you're using Vagrant to run Docker, you'll need to set up Vagrant's port forwarding before we can do any meaningful tests. If you're not using Vagrant, then just skip this step.</p> <h3>Setting Up Vagrant Port Forwards</h3> <p <code>tuts/pyredis</code> Docker instance's port 8080. </p> <p>On your local machine, go back to the folder where you first typed <code>vagrant init</code>. You'll find a text file there called simply <code>Vagrantfile</code>. Open it up in your favorite text editor and look for the following portion:<, host: 8080 </pre> <p>Uncomment the final line and change the ports from 80 and 8080 to <code>8080</code> and <code>9000</code>. The result should look like this:<80, host: 9000 </pre> <p>Now run: </p> <pre class="brush: bash">vagrant reload </pre> <p>... which will cause the Vagrant VM to restart itself with the correct port forwards. Once this is complete, you can run <code>vagrant ssh</code> again and continue the tutorial. </p> <p>Our little <code>pyredis</code> app by default, opens a small web server on port 8080. The following command will let you access port 8080 via port 9000 on your host machine:</p> <pre class="brush: bash">docker run -t -i -p 9000:8080 tuts/pyredis /bin/bash </pre> <p>You'll get a Docker root prompt, so let's start up our app:</p> <pre class="brush: bash">redis-server 2>&1 > /dev/null & python /pyredis/app.py </pre> <p>If all goes well, you'll see the following:</p> <pre class="brush: bash">Bottle v0.11.6 server starting up (using WSGIRefServer())... Listening on Hit Ctrl-C to quit. </pre> <p>This means the server is running. On your local machine, fire up a web browser and point it to <code>localhost:9000</code> (if you're doing this tutorial on a remote server, then make sure you have network access to port 9000 and replace <code>localhost</code> with the address of your web server).</p> <p.</p> <h2>Saving Your Run Config</h2> <p>So this is all great for testing, but the goal here is to be able to deploy your app. You don't want to have to type in the commands to start your app manually each time. </p> <p>Docker again comes to the rescue. When you commit, Docker can automatically save some run info, such as which ports to map and what commands to run when the image starts. This way, all you have to do is type <code>docker <image_name></code> and Docker will take care of the rest. True containerization. </p> <p>For our script, we only have two commands to run at startup:</p> <pre class="brush: bash">redis-server 2>&1 > /dev/null & python /pyredis/app.py </pre> <p>The easiest way to do that is to create a small launch script that runs these two commands. Let's start our <code>tuts/pyredis</code> again and add a small launch script (just directly copy and paste the below, into the Docker prompt):</p> <pre class="brush: bash">docker run -t -i tuts/pyredis /bin/bash cat > /pyredis/launch.sh <&1 > /dev/null & #!/bin/sh python /pyredis/app.py EOF chmod +x /pyredis/launch.sh </pre> <p>This saved the commands we use to launch our Python server into a small bash script called <code>launch.sh</code> and sets the executable bit so that it's easier to run. </p> <p>Now that the script is in the image successfully, from another terminal, commit it so that it will persist (remember to do a <code>docker ps</code> to get your latest container's ID first):</p> <pre class="brush: bash">docker commit tuts/pyrdis </pre> <p>Let's test this. If you exit out of your Docker prompt and run it again with the following command, you should be able to access the pyredis web app at <code>localhost:9000</code>, just like last time.</p> <pre class="brush: bash">docker run -t -i -p 8000:8080 tuts/pyredis /bin/bash /pyredis/launch.sh </pre> <code>docker run <image_name></code> and Docker takes care of the rest. </p> <p>To configure this, you need to pass in some JSON information to the commit command. There are a <a href="">lot of parameters</a> you can use, but for now we'll just concern ourselves with mapping ports and initialization scripts. Fire up your favorite text editor and paste in the following:</p> <pre class="brush: bash">{ "cmd": [ "/bin/bash", "/pyredis/launch.sh" ], "PortSpecs": [ "9000:8080" ] } </pre> <p>This represents the information we typed in the <code>-p</code> option as well as the path to the launch script. One important bit to note is that for the <code>cmd</code> option, every place where you would normally use a space is actually being passed as a separate parameter. </p> <p>Save that JSON snippet to a file called <code>runconfig.json</code> and let's update Docker to use it.</p> <pre class="brush: bash">docker commit -run=$(cat runconfig.json) tuts/pyredis </pre> <p>Now if you do:</p> <pre class="brush: bash">docker run tuts/pyredis </pre> <p>You'll see <code>bottle</code> start up and you can access the app via the browser. </p> <h2>Deploying Public Images to a Server Via the Public Docker Registry</h2> <p. </p> <p>This is pretty straightforward, so I'll refer you to <a href="">Docker's own documentation</a>. If you instead want to deploy privately, then read on to the next section(s).</p> <h2>Deploying Private Images to a Server (the Easy Way)</h2> <p>Great, so now we've got an easy to use Docker image running on your machine. The next step is to deploy it to a server!</p> <p: </p> <ol> <li>You can bypass Docker's repository features entirely and manually transfer images.</li> <li>You can create your own repository. </li> </ol> <p. </p> <p>The first step is to export your container into a <code>.tar</code> archive. You can do this via Docker's <code>export</code> command. To deploy the example app we've been using in this tutorial, you would do something like this:</p> <pre class="brush: bash">docker export > pyredis.tar </pre> <p>Docker will sit and process for some time, but afterwards you will have a <code>pyredis.tar</code> file that contains the image you created. You can then copy <code>pyredis.tar</code> to your server and run the following:</p> <pre class="brush: bash">cat pyredis.tar | Docker import - </pre> <p>Docker will again sit for a while and eventually spit out the ID of the new image it has created. You can <code>commit</code> this to a more memorable name by doing this:</p> <pre class="brush: bash">docker commit tuts/pyredis </pre> <p>Our tutorial app is now deployed and you can run it with the same run command as before:</p> <pre class="brush: bash">docker run -t -i -p 8000:8080 tuts/pyredis /bin/bash /pyredis/launch.sh </pre> <h2>Deploying Private Images to a Server (the Cool Way)</h2> <p>The cooler way to deploy your app is to host your own Docker repository. Get Docker installed on a machine and run the following command:</p> <pre class="brush: bash">docker run -p 5000:5000 samalba/docker-registry </pre> <p>Wait a bit for it to download the pieces and you should soon see some messages about starting unicorn and booting workers. </p> <p</p> <pre class="brush: bash">docker login localhost:5000 </pre> <p>Go ahead and enter in the username, password and email you'd like to use with your Docker repository. </p> <p>In order to push the <code>tuts/pyredis</code> app into the repo, we first have to "tag" it with the private repository address information like so:</p> <pre class="brush: bash">docker tag tuts/pyredis localhost:5000/tuts/pyredis </pre> <p>This tells Docker to create a new "tag" of <code>tuts/pyredis</code> and associate it with the repo running at <code>localhost:5000</code>. You can think of this tag as this image's name in the repository. For consistency, I have kept the names the same and tagged it <code>localhost:5000/tuts/pyredis</code>, but this name could easily be something completely different (like <code>localhost:5000/pyredis_prod</code>.) </p> <p>If you run <code>docker images</code> now, you will see that there's a new image listed with the name <code>localhost:5000/tuts/pyredis</code>. Docker's mechanism for specifying repositories is closely linked to its mechanism for naming (or tagging as Docker puts it), so this is all you need. </p> <p>To push the image we've created into our repository, just do <code>docker push</code> and the full tagged image name (including the address):</p> <pre class="brush: bash">docker push localhost:5000/tuts/pyredis </pre> <p>Docker will connect to your repository running at <code>localhost:5000</code> and start to push your changes. You'll see a lot of messages about the various HTTP requests involved showing up in the other terminal window (the one running <code>samalba/docker-registry</code>), and information about the upload will go by in this one. This will take awhile, so you might want to grab a coffee. </p> <p <code>samalba/docker-registry</code> Docker container.</p> <p>To do this, do the usual <code>docker ps</code> to get the ID of the running <code>samalba/docker-registry</code> container and then commit it to a new container. This isn't ideal, if doing this in production you would want to configure Docker volumes or use the <code>-v</code> option from above to persist the repo's file directly to the server, instead of inside the container, but that's outside the scope of this tutorial.</p> <p>Now for the fun part: deploying our new Docker image on a new server. Since at the time of this writing, Docker repositories don't have any security or authentication mechanisms, we'll do our work over secure SSH tunnels. From the virtual machine where you set up the <code>tuts/pyredis</code> tutorial, <code>ssh</code> into your production server and forward port 5000 like so:</p> <pre class="brush: bash">ssh -R 5000:localhost:5000 -l </pre> <p>The <code>-R</code> flag to <code>ssh</code> means that when you connect to <code>localhost:5000</code> on your production server, SSH will forward the connection back to port 5000 on your virtual machine, which is in turn getting forwarded to the <code>samalba/docker-registry</code> container where our repo is living. </p> <p>If Docker is not installed on this server, go ahead and install it as per the installation directions. Once you have Docker running, deploying your image is as simple as:</p> <pre class="brush: bash">docker pull localhost:5000/tuts/pyredis </pre> :</p> <pre class="brush: bash">docker run tuts/pyredis </pre> <h2>Wrap-Up & Next Steps</h2> <p>So that's the basics of Docker. With this information you can now create and manage Docker images, push and pull them to public and private repos and deploy them to separate servers. </p> <p>This is an intro tutorial, so there are lots of Docker features that weren't covered here. Two of the most notable ones are Dockerfiles and volumes. </p> <p <a href="">own documentation</a>.</p> <p>The second feature is volumes. Volumes work a bit like the shared folders we covered with the <code>-v</code> option, in that they allow Docker containers to persist their data. Unlike folder sharing with <code>-v</code>, they don't share with the host system, but they can be shared between images. You can check out <a href="">this tutorial</a> for a good introduction. <-26T15:00:13.184Z 2014-03-26T15:00:13.184Z Nik van der Ploeg tag:code.tutsplus.com,2005:PostPresenter/cms-20369 Securely Handling User's Login Credentials <p.</p><h2>Securing the Username and Password</h2> <p.</p> <p.<. </p><h3>Disadvantages</h3> <p.</p> <p.</p> <p>Always be careful while using email as the login to not show it publicly, for both privacy reasons and spam prevention issues.</p> <h2>Logins Can Provide Too Much Info</h2> <p <em>and</em> when the password doesn't match the password for the given user.

Ugly code. Complicated code. Spaghetti code. Jibberish nonsense. In two words, <em>Legacy Code</em>. This is a series that will help you work and deal with it.</p> <p>In an ideal world, you would write only new code. You would write it beautiful and perfect. You would never have to revisit your code and you will never have to maintain projects ten years old. In an ideal world...</p> <p.</p> <h2>Definition of Legacy Code</h2> <p.</p> <blockquote>To me, <em>legacy code</em> is simply code without tests. ~ Michael Feathers</blockquote> <p>Well, that is the first formal definition of the expression <em>legacy code</em>, published by Michael Feathers in his book <a href="">Working Effectively with Legacy Code</a>..</p> <h2>Getting Our Legacy Code</h2> <p>This series will be based on the exceptional Trivia Game by <a href="">J.B. Rainsberger</a> designed for <a href="">Legacy Code Retreat</a> events. It is made to be like real legacy code and to also offer opportunities for a wide variety of refactoring, at a decent level of difficulty.</p> <h3>Check Out the Source Code</h3> <p.</p> <pre class="brush: bash"> $.</pre> <p>When you open the <code>trivia</code> directory you will see our code in several programming languages. We will work in PHP, but you are free to choose your favorite one and apply the techniques presented here.</p> <h2>Understanding the Code</h2> <p>By definition, legacy code is difficult to understand, especially if we don't even know what it's supposed to do. So the first step is to run the code and make some kind of reasoning, what it is about.</p> <p>We have two files in our directory.</p> <pre class="brush: bash">$</pre> <p><code>GameRunner.php</code> seems to be a good candidate for our attempt to run the code.</p> <pre class="brush: bash">$.</pre> <p>OK. Our guess was correct. Our code ran and produced some output. Analyzing this output will help us deduce some basic idea about what the code does.</p> <ol> <li>We know it's a Trivia game. We knew it when we checked out the source code.</li> <li>Our example has three players: Chet, Pat and Sue.</li> <li>There is some kind of rolling of a dice or similar concept.</li> <li>There is a current location for a player. Possibly on some kind of board?</li> <li>There are various categories from which questions are asked.</li> <li>Users answer questions.</li> <li>Correct answers give players gold.</li> <li>Wrong answers send players to the penalty box.</li> <li>Players can get out of penalty box, based on some not quite clear logic.</li> <li>It seems like the user that first reaches six gold coins wins.</li> </ol> <p.</p> <h2>Scanning the Code</h2> <p>Now that we have an idea about what the code outputs, we can start looking at it. We will start with the runner.</p> <h3>The Game Runner</h3> <p>I like to start with running all the code through the formatter of my IDE. This greatly improves readability by making the code's form familiar with what I am used to. So this:</p><figure class="post_image"><img alt="" src=""></figure><p>... will become this:<br></p><figure class="post_image"><img alt="" src=""></figure><p>... which is somewhat better. It may not be a huge difference with this small amount of code, but it will be on our next file.<br></p> <p>Looking at our <code>GameRunner.php</code>.</p> <h3>The Game File</h3> <p>We should do the same formatting on the <code>Game.php</code> file also.</p> <p. </p> <h2>The Golden Master</h2> <p>And the thought of change leads us to our lack of tests. The methods we saw in <code>Game.php</code>.</p> <h3>So What Is This Golden Master?</h3> <p.</p> <p.</p> <h3>Writing the Golden Master Generator</h3> <p.</p> <p>You will find in the attached code archive, inside the <code>source</code> folder but outside the <code>trivia</code> folder our <code>Test</code> folder. In this folder, we create a file: <code>GoldenMasterTest.php</code>.</p> <pre class="brush: php">class GoldenMasterTest extends PHPUnit_Framework_TestCase { function testGenerateOutput() { ob_start(); require_once __DIR__ . '/../trivia/php/GameRunner.php'; $output = ob_get_contents(); ob_end_clean(); var_dump($output); } }</pre> <p>We could do this in many ways. We could, for example, run our code from the console and redirect its output to a file. However, having it in a test that is easily run inside our IDE is an advantage we should not ignore.</p> <p>The code is quite simple, it buffers the output and puts it into the <code>$output</code> variable. The <code>require_once()</code> will also run all the code inside the the included file. In our var dump we will see some already familiar output.</p><figure class="post_image"><img alt="" src=""></figure><p>However on a second run, we can observe something odd:<br></p><figure class="post_image"><img alt="" src=""></figure><p>... the outputs differ. Even though we ran the same code, the output is different. The rolled numbers are different, the players' positions are different.<br></p> <h3>Seeding the Random Generator</h3> <pre class="brush: php">do { $aGame->roll(rand(0, 5) + 1); if (rand(0, 9) == 7) { $notAWinner = $aGame->wrongAnswer(); } else { $notAWinner = $aGame->wasCorrectlyAnswered(); } } while ($notAWinner);</pre> <p>By analyzing the essential code from the runner, we can see that it uses a the function <code>rand()</code> to generate random numbers. Our next stop is the official PHP documentation to research this <code>rand()</code> function.</p> <blockquote>The random number generator is seeded automatically.</blockquote> <p>The documentation tells us that seeding happens automatically. Now we have another task. We need to find a way to control the seed. The <code>srand()</code> function can help with that. Here is its definition from the documentation.</p> <blockquote>Seeds the random number generator with seed or with a random value if no seed is given.</blockquote> <p>It tells us, that if we run this before any call to <code>rand()</code>, we should always end up with the same results.</p> <pre class="brush: php">function testGenerateOutput() { ob_start(); srand(1); require_once __DIR__ . '/../trivia/php/GameRunner.php'; $output = ob_get_contents(); ob_end_clean(); var_dump($output); }</pre> <p>We put <code>srand(1)</code> before our <code>require_once()</code>. Now the output is always the same.</p><figure class="post_image"><img alt="" src=""></figure><h3>Put the Output in a File<br></h3> <pre class="brush: php"; } }</pre> <p>This change looks reasonable. Right? We extracted the code generation into a method, run it twice, and expected the output to be equal. However they won't be.</p><figure class="post_image"><img alt="" src=""></figure><p>The reason is that <code>require_once()</code> will not require the same file twice. The second call to the <code>generateOutput()</code> method will produce an empty string. So, what could we do? What if we simply <code>require()</code>? That should be run each time.<br></p><figure class="post_image"><img alt="" src=""></figure><p>Well, that leads to another problem: <code>"Cannot redeclare echoln()"</code>. But where is that coming from? It is right at the beginning of the <code>Game.php</code> file. The reason why this error is occurring is because in <code>GameRunner.php</code> we have <code>include __DIR__ . '/Game.php';</code>, which tries to include the Game file twice, each time when we call the <code>generateOutput()</code> method.<br></p> <pre class="brush: php">include_once __DIR__ . '/Game.php';</pre> <p>Using <code>include_once</code> in <code>GameRunner.php</code> will solve our problem. Yes, we needed to modify <code>GameRunner.php</code> without having tests for it, yet! However, we can be 99% sure that our change will not break the code itself. It is a small and simple enough change to not scare us very much. And most importantly, it makes the tests pass.</p><figure class="post_image"><img alt="" src=""></figure> <h3>Run It Several Times</h3> <p>Now that we have code we can run many times, it's time to generate some output.</p> <pre class="brush: php"--; } }</pre> <p>We extracted another method here: <code>generateMany()</code>..</p> <p>But wait! The same player wins every time? Is that possible?</p> <pre class="brush: bash".</pre> <p>Yes! It is possible! It is more than possible. It is a sure thing. We have the same seed for our random function. We play the same game over and over again.</p> <h3>Run It Differently Each Time</h3> <p.</p> <pre class="brush: php"; }</pre> <p>This still keeps our test passing, so we are sure we generate the same complete output each time, while the output plays a different game for each iteration. </p> <pre class="brush: bash".</pre> <p>There are various winners for the game in a random fashion. This looks good.</p> <h3>Getting to 20,000</h3> <p>The first thing you may try is to run our code for 20,000 game iterations.</p> <pre class="brush: php"); }</pre> <p>This will almost work. Two 55MB files will be generated.</p> <pre class="brush: bash">ls -alh /tmp/gm* -rw-r--r-- 1 csaba csaba 55M Mar 14 20:38 /tmp/gm2.txt -rw-r--r-- 1 csaba csaba 55M Mar 14 20:38 /tmp/gm.txt</pre> <p.</p><figure class="post_image"><img alt="" src=""></figure><p>In other words, we generate good files, but PHPUnit cannot compare them. We need a work-around.<br></p> <pre class="brush: php">$this->assertFileEquals('/tmp/gm.txt', '/tmp/gm2.txt');</pre> <p>That seems to be a good candidate, but it still fails. What a shame. We need to research the situation further.</p> <pre class="brush: php">$this->assertTrue($file_content_gm == $file_content_gm2);</pre> <p>This however, is working.</p><figure class="post_image"><img alt="" src=""></figure><div> <p>It can compare the two strings and fail if they are different. It has however, a small price. It won't be able to exactly tell what is wrong when the strings differ. It will just simply say <code>"Failed asserting that false is true."</code>. But we will deal with that in an upcoming tutorial.</p> <h2>Final Thoughts</h2> <p <code>gm.txt</code> file untouched and generate another one only once per run. But 12 seconds is still a huge amount of time for such a small code base. </p> <p>By the time we finish this series, our tests should run in less than a second and test all the code properly. So, stay tuned for our next tutorial when we will tackle problems like magic constants, magic strings and complex conditionals. Thanks for reading.<-21T15:00:02.747Z 2014-03-21T15:00:02.747Z Patkos Csaba tag:code.tutsplus.com,2005:PostPresenter/cms-20290 Testing Your Ruby Code With Guard, RSpec & Pry: Part 2 <p>Welcome back! If you missed the <a href="" target="_self">first part of our journey</a> so far, then you might want to go back and catch-up first.</p> <p.</p> <h2>Other RSpec Features</h2> <p>Let's take a moment to review some other RSpec features that we've not needed in this simple example application, but you may find useful working on your own project.</p> <h3>Pending Statement</h3> <p>Imagine you write a test but you're interrupted, or you need to leave for a meeting and haven't yet completed the code required to get the test to pass.</p> <p>You could delete the test and re-write it later when you're able to come back to your work. Or alternatively you could just comment the code out, but that's pretty ugly and definitely no good when using a version control system.</p> <p>The best thing to do in this situation is to define our test as 'pending' so whenever the tests are run, the test framework will ignore the test. To do this you need to use the <code>pending</code> keyword:</p> <pre class="brush: ruby">describe "some method" do it "should do something" pending end end </pre> <h3>Set-Up and Tear-Down</h3> <p>All good testing frameworks allow you to execute code before and after each test is run. RSpec is no different. </p> <p>It provides us <code>before</code> and <code>after</code> methods which allows us to set-up a specific state for our test to run, and to then clean up that state after the test has run (this is so the state doesn't leak and effect the outcome of subsequent tests).</p> <pre class="brush: ruby">describe "some method" do before(:each) do # some set-up code end after(:each) do # some tear-down code end it "should do something" pending end end </pre> <h3>Context Blocks</h3> <p>We've already seen the <code>describe</code> block; but there is another block which is functionally equivalent called <code>context</code>. You can use it every where you would use <code>describe</code>.</p> <p>The difference between them is subtle but important: <code>context</code> allows us to define a state for our test. Not explicitly though (we don't actually set the state by defining a <code>context</code> block - it instead is for readability purposes so the intent of the following code is clearer). </p> <p>Here is an example:</p> <pre class="brush: ruby">describe "Some method" do context "block provided" do it "yields to block" do pending end end context "no block provided" do it "calls a fallback method" do pending end end end </pre> <h3>Stubs</h3> <p>We can use the <code>stub</code> method to create a fake version of an existing object and to have it return a pre-determined value.</p> <p>This is useful in preventing our tests from touching live service APIs, and guiding our tests by giving predictable results from certain calls.</p> <p>Imagine we have a class called <code>Person</code> and that this class has a <code>speak</code> method. We want to test that method works how we expect it to. To do this we'll stub the <code>speak</code> method using the following code:</p> <pre class="brush: ruby">describe Person do it "speak()" do bob = stub() bob.stub(:speak).and_return('hello') Person.any_instance.stub(:initialize).and_return(bob) instance = Person.new expect(instance.speak).to eq('hello') end end </pre> <p>In this example, we say that 'any instance' of the <code>Person</code> class should have its <code>initialize</code> method stubbed so it returns the object <code>bob</code>.</p> <p>You'll notice that <code>bob</code> is itself a stub which is set-up so that any time code tries to execute the <code>speak</code> method it will return "hello".</p> <p>We then proceed to create a new <code>Person</code> instance and pass the call of <code>instance.speak</code> into RSpec's <code>expect</code> syntax.</p> <p>We tell RSpec that we're expecting that call to result in the String "hello".</p> <h3>Consecutive Return Values</h3> <p>In the previous examples we've use the RSpec feature <code>and_return</code> to indicate what our stub should return when it's called.</p> <p>We can indicate a different return value each time the stub is called by specifying multiple arguments to the <code>and_return</code> method:</p> <pre class="brush: ruby">obj = stub() obj.stub(:foo).and_return(1, 2, 3) expect(obj.foo()).to eq(1) expect(obj.foo()).to eq(2) expect(obj.foo()).to eq(3) </pre> <h3>Mocks</h3> <p>Mocks are similar to Stubs in that we are creating fake versions of our objects but instead of returning a pre-defined value we're more specifically guiding the routes our objects <em>must</em> take for the test to be valid.</p> <p>To do that we use the <code>mock</code> method:</p> <pre class="brush: ruby">describe Obj do it "testing()" do bob = mock() bob.should_receive(:testing).with('content') Obj.any_instance.stub(:initialize).and_return(bob) instance = Obj.new instance.testing('some value') end end </pre> <p>In the above example we create a new <code>Object</code> instance and then call its <code>testing</code> method.</p> <p>Behind the scenes of that code we expect the <code>testing</code> method to be called with the value <code>'content'</code>. If it isn't called with that value (which in the above example it's not) then we know that some piece of our code hasn't functioned properly.</p> <h3>Subject Block</h3> <p>The <code>subject</code> keyword can be used in a couple of different ways. All of which are designed to reduce code duplication.</p> <p>You can use it implicitly (notice our <code>it</code> block doesn't reference <code>subject</code> at all):</p> <pre class="brush: ruby">describe Array do describe "with 3 items" do subject { [1,2,3] } it { should_not be_empty } end end </pre> <p>You can use it explicitly (notice our <code>it</code> block refers to <code>subject</code> directly):</p> <pre class="brush: ruby">describe MyClass do describe "initialization" do subject { MyClass } it "creates a new instance" do instance = subject.new expect(instance).to be_a(MyClass) end end end </pre> <p>Rather than constantly referencing a subject within your code and passing in different values for instantiation, for example:</p> <pre class="brush: ruby" </pre> <p>You can instead use <code>subject</code> along with <code>let</code> to reduce the duplication:</p> <pre class="brush: ruby" </pre> <p>There are many more features available to RSpec but we've looked at the most important ones that you'll find yourself using a lot when writing tests using RSpec.</p> <h3>Randomized Tests</h3> <p>You can configure RSpec to run your tests in a random order. This allows you to ensure that none of your tests have any reliance or dependency on the other tests around it.</p> <pre class="brush: ruby">RSpec.configure do |config| config.order = 'random' end </pre> <p>You can set this via the command using the <code>--order</code> flag/option. For example: <code>rspec --order random</code>.</p> <p>When you use the <code>--order random</code> <code>1234</code> then execute <code>--order random:1234</code>) and it will use that same randomized seed to see if it can replicate the original dependency bug.</p> <h3>Global Configuration</h3> <p>You've seen we've added a project specific set of configuration objects within our <code>Rakefile</code>. But you can set configuration options globally by added them to a <code>.rspec</code> file within your home directory.</p> <p>For example, inside <code>.rspec</code>:</p> <pre class="brush: plain">--color --format nested </pre> <h2>Debugging With Pry</h2> <p>Now we're ready to start looking into how we can debug our application and our test code using the Pry gem. </p> <p>It's important to understand that although Pry is really good for debugging your code, it is actually meant as an improved Ruby REPL tool (to replace <code>irb</code>) and not strictly debugging purposes; so for example there are no built-in functions such as: step into, step over or step out etc that you would typically find in a tool designed for debugging. </p> <p>But as a debugging tool, Pry is very focused and lean.</p> <p>We'll come back to debugging in a moment, but let's first review how we'll be using Pry initially.</p> <h3>Updated Code Example</h3> <p>For the purpose of demonstrating Pry I'm going to add more code to my example application (this extra code doesn't effect our test in any way)</p> <pre class="brush: ruby">class RSpecGreeter attr_accessor :test @@binding.pry</code>.</p><p>When you run your code you'll notice that the terminal will stop and place you inside your application's code at the exact spot your binding.pry was placed.</p> <p>Below is an example of how it might look...</p> <pre class="brush: bash"> 8: def greet => 9: binding.pry 10: pubs 11: privs 12: "Hello RSpec!" 13: end </pre> <p>From this point Pry has access to the local scope so you can use Pry much like you would in <code>irb</code> and start typing in for example variables to see what values they hold.</p> <p>You can run the <code>exit</code> command to exit Pry and for your code to continue executing.</p> <h3>Finding Where You Are: <code>whereami</code></h3> <p>When using lots of <code>binding.pry</code> break points it can be difficult to understand where in the application you are. </p> <p>To get a better context of where you are at any point, you can use the <code>whereami</code> command. </p> <p>When run on its own you'll see something similar to when you used <code>binding.pry</code> (you'll see the line on which the break-point was set and a couple of lines above and below that). The difference being is if you pass an extra numerical argument like <code>whereami 5</code> you'll see five additional lines above where the <code>binding.pry</code> was placed. You could request to see 100 lines around the current break-point for example.</p> <p>This command can help orientate you within the current file.</p> <h3>Stack Trace: <code>wtf</code></h3> <p>The <code>wtf</code> command stands for "what the f***" and it provides a full stack trace for the most recent exception that has been thrown. It can help you understand the steps leading up to the error that occurred.</p> <h3>Inspecting: <code>ls</code></h3> <p>The <code>ls</code> command displays what methods and properties are available to Pry. </p> <p>When run it will show you something like...</p> <pre class="brush: bash">RSpecGreeter#methods: greet pubs test test= class variables: @@class_property locals: _ __ _dir_ _ex_ _file_ _in_ _out_ _pry_ </pre> <p>In the above example we can see that we have four public methods (remember we updated our code to include some additional methods and then <code>test</code> and <code>test=</code> were created when using Ruby's <code>attr_accessor</code> short hand).</p> <p>It also displays other class and local variables Pry can access.</p> <p>Another useful thing you can do is to grep (search) the results for only what you're interested in. You'll need to have an understanding of <a href="">Regular Expressions</a> but it can be a handy technique. Here is an example...</p> <pre class="brush: bash">ls -p -G ^p => RSpecGreeter#methods: privs </pre> <p>In the above example we're using the <code>-p</code> and <code>-G</code> options/flags which tell Pry we only want to see public and private methods and we use the regex <code>^p</code> (which means match anything starting with <code>p</code>) as our search pattern to filter the results.</p> <p>Running <code>ls --help</code> will also show you all available options.</p> <h3>Changing Scope: <code>cd</code></h3> <p>You can change the current scope by using the <code>cd</code> command.</p> <p>In our example if we run <code>cd ../pubs</code> it'll take us to the result of that method call.</p> <p>If we now run <code>whereami</code> you'll see it will display <code>Inside "I'm a test variable"</code>.</p> <p>If we run <code>self</code> then you'll see we get <code>"I'm a test variable"</code> returned.</p> <p>If we run <code>self.class</code> we'll see <code>String</code> returned.</p> <p>You can move up the scope chain using <code>cd ..</code> or you can go back to the top level of the scope using <code>cd /</code>.</p> <p>Note: we could add another <code>binding.pry</code> inside the <code>pubs</code> method and then our scope would be inside that method rather than the result of the method.</p> <h3>Seeing How Deep You Are: <code>nesting</code></h3> <p>Consider the previous example of running <code>cd pubs</code>. If we run the <code>nesting</code> command we'll get a top level look on the number of contexts/levels Pry currently has:</p> <pre class="brush: bash">Nesting status: -- 0. # (Pry top level) 1. "I'm a test variable" </pre> <p>From there we can run <code>exit</code> to move back to the earlier context (for example, inside the <code>greet</code> method)</p> <p>Running <code>exit</code> again will mean we're closing the last context Pry has and so Pry finishes and our code continues to run.</p> <h3>Locate Any Method: <code>find-method</code></h3> <p>If you're not sure where to find a particular method then you can use the <code>find-method</code> command to show you all files within your code base that has a method that matches what you're searching for:</p> <pre class="brush: bash">find-method priv => Kernel Kernel#private_methods Module Module#private_instance_methods Module#private_constant Module#private_method_defined? Module#private_class_method Module#private RSpecGreeter RSpecGreeter#privs </pre> <p>You can also use the <code>-c</code> option/flag to search the content of files instead:</p> <pre class="brush: bash">find-method -c greet => RSpecGreeter RSpecGreeter: def greet RSpecGreeter#privs: greet </pre> <h3>Classic Debugging: <code>next</code>, <code>step</code>, <code>continue</code></h3> <p>Although the above techniques are useful, it's not really 'debugging' in the same sense as what you're probably used to.</p> <p>For most developers their editor or browser will provide them with a built-in debugging tool that lets them actually step through their code line by line and follow the route the code takes until completion.</p> <p>As Pry is developed to be used as a REPL that's not to say it's not useful for debugging. </p> <p>A naive solution would be to set multiple <code>binding.pry</code> statements through out a method and use <strong>ctrl-d</strong> to move through each break-point set. But that' still not quite good enough.</p> <p>For step by step debugging you can load the gem <a href="">pry-nav</a>...</p> <pre class="brush: ruby">source "" gem 'rspec' group :development do gem 'guard' gem 'guard-rspec' gem 'pry' # Adds debugging steps to Pry # continue, step, next gem 'pry-remote' gem 'pry-nav' end </pre> <p>This gem extends Pry so it understands the following commands:</p> <ul> <li><code>Next</code> (move to the next line)</li> <li><code>Step</code> (move to the next line and if it's a method, then move into that method)</li> <li><code>Continue</code> (Ignore any further break-points in this file)</li> </ul> <h2>Continuous Integration With Travis-CI</h2> <p>As an added bonus let's integrate our tests with the online CI (continuous integration) service <a href="">Travis-CI</a>.</p> <p.</p> ).</p> <p>Regardless, code should never be pushed directly to your live production server any way; it should always be pushed first to a CI server to help catch any potential bugs that arise from differences between your development environment and the production environment. </p> <p>A lot of companies have more environments still for their code to pass through before it reaches the live production server. </p> <p>For example, at BBC News we have:</p> <ul> <li>CI</li> <li>Test</li> <li>Stage</li> <li>Live</li> </ul> <p>Although each environment should be identical in set-up, the purpose is to implement different types of testing to ensure as many bugs are caught and resolved before the code reaches 'live'.</p> <h3>Travis-CI</h3> <p>Travis CI is a hosted continuous integration service for the open source community. It is integrated with GitHub and offers first class support for multiple languages</p> <p>What this means is that Travis-CI offers free CI services for open-source projects and also has a paid model for businesses and organizations who want to keep their CI integration private.</p> <p>We'll be using the free open-source model on our example GitHub repository.</p> <p>The process is this: </p> <ul> <li>Register an account with <a href="">GitHub</a></li> <li>Sign into <a href="">Travis-CI</a> using your GitHub account</li> <li>Go to your "<a href="">Accounts</a>" page</li> <li>Turn "on" any repositories you want to run CI on</li> <li>Create a <code>.travis.yml</code> file within the root directory of your project and commit it to your GitHub repository</li> </ul> <p>The final step is the most important (creating a <code>.travis.yml</code> file) as this determines the configuration settings for Travis-CI so it knows how to handle running the tests for your project.</p> <p>Let's take a look at the <a href=""><code>.travis.yml</code></a> file we're using for our example GitHub repository:</p> <pre class="brush: bash">language: ruby cache: bundler rvm: - 2.0.0 - 1.9.3 script: 'bundle exec rake spec' bundler_args: --without development branches: only: - master notifications: email: - [email protected] </pre> <p>Let's break this down piece by piece...</p> <p>First we specify what language we're using in our project. In this case we're using Ruby: <code>language: ruby</code>.</p> <p>Because running Bundler can be a bit slow and we know that our dependencies aren't going to change that often we can choose to cache the dependencies, so we set <code>cache: bundler</code>.</p> <p>Travis-CI uses <a href="">RVM (Ruby Version Manager)</a> for installing Rubies on their servers. So we need to specify what Ruby versions we want to run our tests against. In this instance we've chosen <code>2.0</code> and <code>1.9.3</code> which are two popular Ruby versions (technically our application uses Ruby 2 but it's good to know our code passes in other versions of Ruby as well):</p> <pre class="brush: bash">rvm: - 2.0.0 - 1.9.3 </pre> <p>To run our tests we know that we can use the command <code>rake</code> or <code>rake spec</code>. Travis-CI by default runs the command <code>rake</code> but because of how Gems are installed on Travis-CI using Bundler we need to change the default command: <code>script: 'bundle exec rake spec'</code>. If we didn't do this then Travis-CI would have an issue locating the <code>rspec/core/rake_task</code> file which is specified within our <code>Rakefile</code>.</p> <p <code>rake</code> command and the suggestion of overwriting the default with <code>bundle exec rake</code> resolved that issue.</p> <p>Next, because we're only interested in running our tests we can pass additional arguments to Travis-CI to filter gems we don't want to bother installing. So for us we want to exclude installing the gems grouped as development: <code>bundler_args: --without development</code> (this means we are excluding gems that are only really used for development and debugging such as Pry and Guard).</p> <p>It's important to note that originally I was loading Pry within our <code>spec_helper.rb</code> file. This caused a problem when running the code on Travis-CI, now that I was excluding 'development' gems. So I had to tweak the code like so:</p> <pre class="brush: ruby">require 'pry' if ENV['APP_ENV'] == 'debug' </pre> <p>You can see that now the Pry gem is only <code>require</code>'ed if an environment variable of <code>APP_ENV</code>:</p> <pre class="brush: bash">APP_ENV=debug && ruby lib/example.rb</pre> <p>There were two other changes I made and that was to our <code>Gemfile</code>. One was to make it clearer what gems were required for testing and which were required for development, and the other was explicitly required by Travis-CI:</p> <pre class="brush: ruby">source "" group :test do gem 'rake' gem 'rspec' end group :development do gem 'guard' gem 'guard-rspec' gem 'pry' # Adds debugging steps to Pry # continue, step, next gem 'pry-remote' gem 'pry-nav' end </pre> <p>Looking at the above updated <code>Gemfile</code> we can see we've moved the RSpec gem into a new <code>test</code> group, so now it should be clearer what purpose each gem has. We've also added a new <code>gem 'rake'</code>. The Travis-CI documentation states this needed to be specified explicitly.</p> <p <code>master</code> branch:</p> <pre class="brush: bash">branches: only: - master </pre> <p>We could tell it to run every branch 'except' a particular branch, like so:</p> <pre class="brush: bash">branches: except: - some_branch_I_dont_want_run </pre> <p>The final section tells Travis-CI where to send notifications to when a build fails or succeeds:</p> <pre class="brush: bash">notifications: email: - [email protected] </pre> <p>You can specify multiple email addresses if you wish:</p> <pre class="brush: bash">notifications: email: - [email protected] - [email protected] - [email protected] </pre> <p>You can be more specific and specify what you want to happen on either a failure or a success (for example, more people will only be interested if the tests fail rather than getting an email every time they pass):</p> <pre class="brush: bash">notifications: email: recipients: - [email protected] on_failure: change on_success: never </pre> <p>The above example shows that the recipient will never receive an email if the tests pass but will get notified if the failure status changes (the default value for both is <code>always</code> which means you'll always be notified regardless of what the status result).</p> <p>Note: when you explicitly specify a <code>on_failure</code> or <code>on_success</code> you need to move the email address(es) inside of <code>recipients</code> key.</p> <h2>Conclusion</h2> <p>This is the end of our two part look into RSpec, TDD and Pry. </p> <p.</p> <p>Hopefully this has given you enough of a taste so you are keen to investigate each of these techniques-19T15:00:07.039Z 2014-03-19T15:00:07.039Z Mark McDonnell tag:code.tutsplus.com,2005:PostPresenter/cms-20072 Revisiting JavaScript Minification <p>Lately I've been seeing that many developers are not minifying their JavaScript code.

Then perhaps you are more interested in a structure like the one postgresql uses, where there is a namespace in /etc and /var/lib for the specific instance of postgres. All, however, are run as the same system user. Also, I'll note that a well designed packaging system should _never_ blindly overwrite already existing files in /etc, so I would implement your case as: * Install predefined configuration files in /etc * Install daemon package -- Brian Sutherland | https://mail.python.org/pipermail/web-sig/2007-March/002608.html | CC-MAIN-2014-15 | en | refinedweb |
Report Server Folder Hierarchy
The report server folder namespace is a hierarchy that contains predefined and user-defined folders. The namespace uniquely identifies reports and other items that are stored in a report server. It provides an addressing scheme for specifying reports in a URL.
Conceptually, this folder hierarchy is similar to the folder hierarchy in the Windows file system. In Reporting Services, however, the folders you work with are virtual folders that are accessed over a Web connection. Neither the folders nor their contents actually exist in a file system. Instead, they exist on a report server, and they appear as folders and items when you access the report server through a browser or a Web-enabled application. When you select or locate a report, the path becomes part of the URL for that report.
Predefined folders are reserved by Reporting Services; they cannot be moved, renamed, or deleted. The following table describes predefined folders that anchor the folder hierarchy and provide a framework for several features.
User-defined folders include any folders created by a user or report server administrator with permission to add items to a folder. For more information about creating folders and folder naming conventions, see Creating, Modifying, and Deleting Folders.
Folders can contain a variety of items. Each type of item has an associated icon that distinguishes it from other items. For more information, see Icons in Report Manager. | http://technet.microsoft.com/en-us/library/ms159783(v=sql.90).aspx | CC-MAIN-2014-15 | en | refinedweb |

Hello,
I like to exchange the icon of a commanddata plugin. For objects it's working fine with the MSG_GETCUSTOMICON message and set it in GetCustomIconData. But not for a commanddata.
I recieve this message also, but it's not updated the icon.
How does it works for commanddata plugins?

OAuth2 Support¶
Kubernetes Web View support OAuth2 for protecting its web frontend. Use the following environment variables to enable it:
OAUTH2_AUTHORIZE_URL
- OAuth 2 authorization endpoint URL, e.g.
OAUTH2_ACCESS_TOKEN_URL
- Token endpoint URL for the OAuth 2 Authorization Code Grant flow, e.g.
OAUTH2_CLIENT_ID
- OAuth 2 client ID
OAUTH2_CLIENT_ID_FILE
- Path to file containing the client ID. Use this instead of
OAUTH2_CLIENT_IDto read the client ID dynamically from file.
OAUTH2_CLIENT_SECRET
- OAuth 2 client secret
OAUTH2_CLIENT_SECRET_FILE
- Path to file containing the client secret. Use this instead of
OAUTH2_CLIENT_SECRETto read the client secret dynamically from file.
SESSION_SECRET_KEY
- Secret to encrypt the session cookie. Must be 32 bytes base64-encoded. Use
cryptography.fernet.Fernet.generate_key()to generate such a key.
OAUTH2_SCOPE
- Scope for the OAuth 2 Authorization eg: ‘email openid profile’ for open ID or Azure AD, ‘’ Note: this field is mandatory for Azure Active Directory
The OAuth2 login flow will (by default) just protect the web frontend, the configured credentials (in-cluster Service Account, Kubeconfig, or Cluster Registry) will be used to access the cluster(s).
This behavior can be changed and the session’s OAuth2 access token can be used for cluster authentication instead of using configured credentials.
Enable this operation mode via
--cluster-auth-use-session-token.
The OAuth redirect flow will not do any extra authorization by default, i.e. everybody who can login with your OAuth provider can use Kubernetes Web View!
You can plug in a custom Python hook function (coroutine) via
--oauth2-authorized-hook to validate the login or do any extra work (store extra info in the session, deny access, log user ID, etc).
Note that the hook needs to be a coroutine function with signature like
async def authorized(data, session). The result should be boolean true if the login is successful, and false otherwise.
Examples of such hooks are provided in the examples directory. A minimal
hooks.py would look like:
import logging async def oauth2_authorized(data: dict, session): access_token = data["access_token"] # TODO: do something with the access token, e.g. look up user info logging.info("New OAuth login!") # TODO: validate whether login is allowed or not return True # allow all OAuth logins
This file would need to be in the Python search path, e.g. as
hooks.py in the root (“/”) of the Docker image. Pass the hook function as
--oauth2-authorized-hook=hooks.oauth2_authorized to Kubernetes Web View.
Google OAuth Provider¶
This section explains how to use the Google OAuth 2.0 provider with Kubernetes Web View:
- follow the instructions on to obtain OAuth 2.0 credentials such as client ID and client secret
- use
https://{my-kube-web-view-host}/oauth2/callbackas one of the Authorized redirect URIs in the Google API Console
- use “” for
OAUTH2_AUTHORIZE_URL
- use “” for
OAUTH2_ACCESS_TOKEN_URL
- pass the obtained client ID in the
OAUTH2_CLIENT_IDenvironment variable
- pass the obtained client secret in the
OAUTH2_CLIENT_SECRETenvironment variable
GitHub OAuth Provider¶
How to use GitHub as the OAuth provider with Kubernetes Web View:
- create a new OAuth app in the GitHub UI
- use
https://{my-kube-web-view-host}/oauth2/callbackas the Authorization callback URL in the GitHub UI
- use “” for
OAUTH2_AUTHORIZE_URL
- use “” for the
OAUTH2_ACCESS_TOKEN_URL
- pass the obtained client ID in the
OAUTH2_CLIENT_IDenvironment variable
- pass the obtained client secret in the
OAUTH2_CLIENT_SECRETenvironment variable
Note that any GitHub user can now login to your deployment of Kubernetes Web View! You have to configure a
--oauth2-authorized-hook function to validate the GitHub login and only allow certain usernames:
- copy
hooks.pyfrom
examples/oauth2-validate-github-token/hooks.py(see examples dir) to a new folder
- customize the username in
hooks.pyto match your allowed GitHub user logins
- create a new
Dockerfilein the same folder
- edit the
Dockerfileto have two lines: 1)
FROM hjacobs/kube-web-view:{version}(replace “{version}”!) as the first line, and 2)
COPY hooks.py /to copy our OAuth validation function
- build the Docker image
- configure your kube-web-view deployment and add
--oauth2-authorized-hook=hooks.oauth2_authorizedas argument
- deploy kube-web-view with the new Docker image and CLI option
AWS Cognito Provider¶
Setting up Cognito¶
A number of steps need to be taken to setup Amazon Cognito for OAuth2. These instructions are correct as of August 2019.
Create User Pool¶
- Create a User Pool
- Choose how you want End Users to sign in (for example via Email, Username or otherwise)
- Once you have gone through all the settings (customise to your liking) for creating a user pool, add an App Client
Create an App Client¶
- Choose a Name that is relevant to the application (eg kube-web-view)
- Make sure the Generate client secret option is selected, and set your Refresh token expiration time to whatever you are comfortable with.
The App Client will then generate a Client ID and Client Secret, wich will be used later
App Client Settings¶
- Select the previously created client
- Fill in the Callback URL(s) section with
https://{my-kube-web-view-host}/oauth2/callback
- Under OAuth 2.0, choose the relevant Allowed OAuth Flows (eg Authorization Code Grant, Implicit Grant)
- Choose the Allowed OAuth Scopes you want to include. email is the minimum you will need
IMPORTANT: Domain Name¶
You must create a domain name for OAuth to function against AWS Cognito, otherwise the required Authorization and Token URLs will not be exposed.
You can choose whether to use an AWS-hosted Cognito Domain (eg
https://{your-chosen-domain}.auth.us-east-1.amazoncognito.com), or to use your own domain.
Update Deployment¶
You can now update your Deployment with the relevant Environment variables. If you have chosen to use an AWS Cognito Domain, then the
{FQDN} variable in the below section will be
https://{your-chosen-domain}.auth.{aws-region}.amazoncognito.com. Otherwise, replace it with your domain
- use “https://{FQDN}/oauth2/authorize” for
OAUTH2_AUTHORIZE_URL
- use “https://{FQDN}/oauth2/token” for
OAUTH2_ACCESS_TOKEN_URL
- Use the App Client ID generated during “Create an App Client” in the
OAUTH2_CLIENT_IDenvironment variable
- Use the App Client secret in the
OAUTH2_CLIENT_SECRETenvironment variable. If you cannot see the secret, press “Show Details” in the AWS Console
Terraform¶
An example Terraform deployment of the above is below:
# Create the User Pool resource "aws_cognito_user_pool" "kube-web-view" { name = "userpool-kube-web-view" alias_attributes = [ "email", "preferred_username" ] auto_verified_attributes = [ "email" ] schema { attribute_data_type = "String" developer_only_attribute = false mutable = true name = "name" required = true string_attribute_constraints { min_length = 3 max_length = 70 } } admin_create_user_config { allow_admin_create_user_only = true } tags = { "Name" = "userpool-kube-web-view" } } # Create the oauth2 Domain resource "aws_cognito_user_pool_domain" "kube-web-view" { domain = "oauth-kube-web-view" user_pool_id = aws_cognito_user_pool.kube-web-view.id } # kube-web-view Client resource "aws_cognito_user_pool_client" "kube-web-view" { name = "kube-web-view" user_pool_id = aws_cognito_user_pool.kube-web-view.id allowed_oauth_flows = [ "code", "implicit" ] allowed_oauth_scopes = [ "email", "openid", "profile", ] supported_identity_providers = [ "COGNITO" ] generate_secret = true allowed_oauth_flows_user_pool_client = true callback_urls = [ "https://{my-kube-web-view-host}/oauth2/callback" ] } # Outputs output "kube-web-view-id" { description = "Kube Web View App ID" value = aws_cognito_user_pool_client.kube-web-view.id } output "kube-web-view-secret" { description = "Kube Web View App Secret" value = aws_cognito_user_pool_client.kube-web-view.client_secret | https://kube-web-view.readthedocs.io/en/latest/oauth2.html | CC-MAIN-2020-40 | en | refinedweb |
Automate Hyperparameter Tuning for your models
When we create our machine learning models, a common task that falls on us is how to tune them.
People end up taking different manual approaches. Some of them work, and some don’t, and a lot of time is spent in anticipation and running the code again and again.
So that brings us to the quintessential question: Can we automate this process?
A while back, I was working on an in-class competition from the “How to win a data science competition” Coursera course. Learned a lot of new things, one among them being Hyperopt — A bayesian Parameter Tuning Framework.
And I was amazed. I left my Mac with hyperopt in the night. And in the morning I had my results. It was awesome, and I did avoid a lot of hit and trial.
This post is about automating hyperparameter tuning because our time is more important than the machine.
So, What is Hyperopt?
From the Hyperopt site:
Hyperopt is a Python library for serial and parallel optimization over awkward search spaces, which may include real-valued, discrete, and conditional dimensions
In simple terms, this means that we get an optimizer that could minimize/maximize any function for us. For example, we can use this to minimize the log loss or maximize accuracy.
All of us know how grid search or random-grid search works.
A grid search goes through the parameters one by one, while a random search goes through the parameters randomly.
Hyperopt takes as an input space of hyperparameters in which it will search and moves according to the result of past trials.
Thus, Hyperopt aims to search the parameter space in an informed way.
I won’t go in the details. But if you want to know more about how it works, take a look at this paper by J Bergstra. Here is the documentation from Github.
Our Dataset
To explain how hyperopt works, I will be working on the heart dataset from UCI precisely because it is a simple dataset. And why not do some good using Data Science apart from just generating profits?
This dataset predicts the presence of a heart disease given some variables.
This is a snapshot of the dataset :
This is how the target distribution looks like:
Hyperopt Step by Step
So, while trying to run hyperopt, we will need to create two Python objects:
An Objective function: The objective function takes the hyperparameter space as the input and returns the loss. Here we call our objective function
objective
A dictionary of hyperparams: We will define a hyperparam space by using the variable
spacewhich is actually just a dictionary. We could choose different distributions for different hyperparameter values.
In the end, we will use the
fmin function from the hyperopt package to minimize our
objective through the
space.
You can follow along with the code in this Kaggle Kernel.
1. Create the objective function
Here we create an objective function which takes as input a hyperparameter space:
We first define a classifier, in this case, XGBoost. Just try to see how we access the parameters from the space. For example
space[‘max_depth’]
We fit the classifier to the train data and then predict on the cross-validation set.
We calculate the required metric we want to maximize or minimize.
Since we only minimize using
fminin hyperopt, if we want to minimize
loglosswe just send our metric as is. If we want to maximize accuracy we will try to minimize
-accuracy
from sklearn.metrics import accuracy_score from hyperopt import hp, fmin, tpe, STATUS_OK, Trials import numpy as np import xgboost as xgb def objective(space): # Instantiate the classifier clf = xgb.XGBClassifier)] # Fit the classsifier clf.fit(X, y, eval_set=eval_set, eval_metric="rmse", early_stopping_rounds=10,verbose=False) # Predict on Cross Validation data pred = clf.predict(Xcv) # Calculate our Metric - accuracy accuracy = accuracy_score(ycv, pred>0.5) # return needs to be in this below format. We use negative of accuracy since we want to maximize it. return {'loss': -accuracy, 'status': STATUS_OK }
2. Create the Space for your classifier
Now, we create the search space for hyperparameters for our classifier.
To do this, we end up using many of hyperopt built-in functions which define various distributions.
As you can see in the code below, we use uniform distribution between 0.7 and 1 for our
subsample hyperparameter. We also give a label for the subsample parameter
x_subsample. You need to provide different labels for each hyperparam you define. I generally add a
x_ before my parameter name to create this label.) }
You can also define a lot of other distributions too. Some of the most useful stochastic expressions currently recognized by hyperopt’s optimization algorithms are:
hp.choice(label, options)— Returns one of the options, which should be a list or tuple.
hp.randint(label, upper)— Returns a random integer in the range [0, upper).
hp.uniform(label, low, high)— Returns a value uniformly between low and high.
hp.quniform(label, low, high, q)— Returns a value like round(uniform(low, high) / q) * q
hp.normal(label, mu, sigma)— Returns a real value that’s normally-distributed with mean mu and standard deviation sigma.
There are a lot of other distributions. You can check them out here.
3. And finally, Run Hyperopt
Once we run this, we get the best parameters for our model. Turns out we achieved an accuracy of 90% by just doing this on the problem.
trials = Trials() best = fmin(fn=objective, space=space, algo=tpe.suggest, max_evals=10, trials=trials) print(best)
Now we can retrain our XGboost algorithm with these best params, and we are done.
Conclusion
Running the above gives us pretty good hyperparams for our learning algorithm. And that saves me a lot of time to think about various other hypotheses and testing them.
I tend to use this a lot while tuning my models. From my experience, the most crucial part in this whole procedure is setting up the hyperparameter space, and that comes by experience as well as knowledge about the models.
So, Hyperopt is an awesome tool to have in your repository but never neglect to understand what your models does. It will be very helpful in the long run.

Alert
Alerts are used to communicate a state that affects a system, feature or page.
See
CAlert's accessibility report
Chakra UI Vue exports 4 Alert related components.
CAlert: The wrapper for alert components.
CAlertIcon: The visual icon for the alert that changes based on the
statusprop.
CAlertTitle: The title of the alert to be announced by screen readers.
CAlertDescription: The description of the alert to be announced by screen readers.
import { CAlert, CAlertIcon, CAlertTitle, CAlertDescription, } from "@chakra-ui/vue";
<c-alert <c-alert-icon /> <c-alert-title :Your browser is outdated!</c-alert-title> <c-alert-description>Your Chakra experience may be degraded.</c-alert-description> <c-close-button </c-alert>
The status of the alerts can be changed by passing the
status prop. This affects the
CAlert's color scheme and icon used.
CAlert supports
error,
success,
warning, and
info statuses.
<c-stack> <c-alert <c-alert-icon /> Chakra is going live on April 15th. Get ready! </c-alert> <c-alert <c-alert-icon /> Sage mode chakra successfully infused. </c-alert> <c-alert <c-alert-icon /> Using Amaterasu is irreversible. Proceed with caution. </c-alert> <c-alert <c-alert-icon /> Unable to load Rasen-Shuriken. Please try again. </c-alert> </c-stack>
You can also use custom Alert icons by passing the name of the icon in the
name prop of the
CAlertIcon. Click here to see how to add icons to your Chakra app.
<c-alert> <c-alert-icon <c-alert-title :Kakashi Sensei followed you.</c-alert-title> <c-alert-description>Follow Kakashi to see his Kamui in action.</c-alert-description> <c-close-button </c-alert>
The
CAlert component has 4 variant styles you can use. Pass the

So I'm making a 2D Space Shooter game, and I'm having my player shoot lots of types of bullets by using Instantiate to clone from a prefab, but the bullet keeps damaging my ship because even though the prefab is set to my "Player" layer (as well as my ship) and Player/Player collision is turned off, the bullet still hits me, which I eventually discovered is because it's cloning it onto the default layer instead of Player.
Is there any way I can force the bullet to clone onto the correct layer?
My full C# PlayerShooting.cs script (which is on the player) is this, in case it helps:
public class PlayerShooting : MonoBehaviour {
public GameObject bulletPrefab;
public float fireDelay;
float cooldownTimer = 0;
void Update () {
cooldownTimer -= Time.deltaTime;
if (Input.GetButtonDown ("Fire1") && cooldownTimer <= 0) {
// Bullet fires:
gameObject.layer = 10;
Instantiate(bulletPrefab, transform.position, transform.rotation);
gameObject.layer = 8;
Debug.Log("Fired!");
//Cooldown Timer is reset:
cooldownTimer = fireDelay;
}
}
}
gameObject.layer = LayerMask.NameToLayer("Player");
Try that.
Where do I put it in the script? I tried putting the bullet onto the player layer in my bullet movement script within Start() but by the time that script had the chance to run the bullet had of course been created, then destroyed by damaging my ship...
GameObject bullet = Instantiate(bulletPrefab, transform.position, transform.rotation) as GameObject;
bullet.layer = LayerMask.NameToLayer("Player");
Still not sure why it spawns it onto the default layer though...
Just added that then realised that whenever I press play it switches every object onto the default layer, not just the bullet. That seems even weirder... Any ideas?

As Vintar said above, you need to make sure you are setting the layer on your instantiated object.
However, as a general rule you don't want to be instantiating a bullet every time one is fired, instead you should consider making a bullet pool containing a number of bullets (depending on how many you expect to see on screen at any one time) and simply enable or disable these as you need them. A quick method for this is to just have an array of bullet game objects created. When you need to fire, find the next currently disabled bullet, enable it, position it correctly and then rather than destroying it when you don't need it anymore, just clones arent behaving the same as the prefab

Technical Analysis
Overview
For Salt Master before 2019.2.4 and 3000 before 3000.2 there is potential for RCE as root.
If a salt-master has its ZeroMQ ports
4506 exposed to the public it is possible for an unauthenticated user to gain access to the root_key. With access to the root key it is possible to run a wide range of salt commands that include file read, file write and command execution. These commands can be executed on the salt-master and any minion that is connected.
This requires multiple socket requests. one to read the key and then additional requests to create jobs.
Proof Of Concept
This POC was tested on SaltStack 2019.2.0
As of the time of writing this assessment I have been able to create a functional exploit POC. The Code can be found here –
The POC and others I am sure will appear shortly has the following functionality
- Read the root key
- Read and Write files on the Salt Master
- Construct a payload to gain full RCE as root on any connected Minion
This took several hours and is “easy” with the available information and access to a test instance. Details on the discovery process can be found on our blog –
Mitigations:
Patch to the latest versions and do not expose theses ports to the external network.
Detections
examine
/var/cache/salt/master/jobs/ on the salt master for a listing of all jobs. the

Classes and objects: the bread-and-butter of many a developer. Object-oriented programming is one of the mainstays of modern programming, so it shouldn't come as a surprise that Python is capable of it.
But if you've done object-oriented programming in any other language before coming to Python, I can almost guarantee you're doing it wrong.
Hang on to your paradigms, folks, it's going to be a bumpy ride.
Class Is In Session
Let's make a class, just to get our feet wet. Most of this won't come as a surprise to anyone.
class Starship(object): sound = "Vrrrrrrrrrrrrrrrrrrrrr" def __init__(self): self.engines = False self.engine_speed = 0 self.shields = True def engage(self): self.engines = True def warp(self, factor): self.engine_speed = 2 self.engine_speed *= factor @classmethod def make_sound(cls): print(cls.sound)
Once that's declared, we can create a new instance, or object, from this class. All of the member functions and variables are accessible using dot notation.
uss_enterprise = Starship() uss_enterprise.warp(4) uss_enterprise.engage() uss_enterprise.engines >>> True uss_enterprise.engine_speed >>> 8
Wow, Jason, I knew this was supposed to be 'dead simple', but I think you just put me to sleep.
No surprises there, right? But look again, not at what is there, but what isn't there.
You can't see it? Okay, let's break this down. See if you can spot the surprises before I get to them.
Declaration
We start with the definition of the class itself:
class Starship(object):
Python might be considered one of the more truly object-oriented languages, on account of its design principle of "everything is an object." All other classes inherit from that
object class.
Of course, most Pythonistas really hate boilerplate, so as of Python 3, we can also just say this and call it good:
class Starship:
Personally, considering The Zen of Python's line about "Explicit is better than implicit," I like the first way. We could debate it until the cows come home, really, so let's just make it clear that both approaches do the same thing in Python 3, and move on.
Legacy Note: If you intend your code to work on Python 2, you must say
(object).
Methods
I'm going to jump down to this line...
def warp(self, factor):
Obviously, that's a member function or method. In Python, we pass
self as the first parameters to every single method. After that, we can have as many parameters as we want, the same as with any other function.
We actually don't have to call that first argument
self; it'll work the same regardless. But, we always use the name
self there anyway, as a matter of style. There exists no valid reason to break that rule.
"But, but...you literally just broke the rule yourself! See that next function?"
@classmethod def make_sound(cls):
You may remember that in object-oriented programming, a class method is one that is shared between all instances of the class (objects). A class method never touches member variables or regular methods.
If you haven't already noticed, we always access member variables in a class via the dot operator:
self.. So, to make it extra-super-clear we can't do that in a class method, we call the first argument
cls. In fact, when a class method is called, Python passes the class to that argument, instead of the object.
As before, we can call
cls anything we want, but that doesn't mean we should.
For a class method, we also MUST put the decorator
@classmethod on the line just above our function declaration. This tells the Python language that you're making a class method, and that you didn't just get creative with the name of the
self argument.
Those methods above would get called something like this...
uss_enterprise = Starship() # Create our object from the starship class # Note, we aren't passing anything to 'self'. Python does that implicitly. uss_enterprise.warp(4) # We can call class functions on the object, or directly on the class. uss_enterprise.make_sound() Starship.make_sound()
Those last two lines will both print out "Vrrrrrrrrrrrrrrrrrrrrr" the exact same way. (Note that I referred to
cls.sound in that function.)
...
What?
Come on, you know you made sound effects for your imaginary spaceships when you were a kid. Don't judge me.
Class vs Static Methods
The old adage is true: you don't stop learning until you're dead. Kinyanjui Wangonya pointed out in the comments that one didn't need to pass
cls to "static methods" - the phrase I was using in the first version of this article.
Turns out, he's right, and I was confused!
Unlike many other languages, Python distinguishes between static and class methods. Technically, they work the same way, in that they are both shared among all instances of the object. There's just one critical difference...
A static method doesn't access any of the class members; it doesn't even care that it's part of the class! Because it doesn't need to access any other part of the class, it doesn't need the
cls argument.
Let's contrast a class method with a static method:
@classmethod def make_sound(cls): print(cls.sound) @staticmethod def beep(): print("Beep boop beep")
Because
beep() needs no access to the class, we can make it a static method by using the
@staticmethod decorator. Python won't implicitly pass the class to the first argument, unlike what it does on a class method (
make_sound())
Despite this difference, you call both the same way.
uss_enterprise = Starship() uss_enterprise.make_sound() >>> Vrrrrrrrrrrrrrrrrrrrrr Starship.make_sound() >>> Vrrrrrrrrrrrrrrrrrrrrr uss_enterprise.beep() >>> Beep boop beep Starship.beep() >>> Beep boop beep
Initializers and Constructors
Every Python class needs to have one, and only one,
__init__(self) function. This is called the initializer.
def __init__(self): self.engine_speed = 1 self.shields = True self.engines = False
If you really don't need an initializer, it is technically valid to skip defining it, but that's pretty universally considered bad form. In the very least, define an empty one...
def __init__(self): pass
While we tend to use it the same way as we would a constructor in C++ and Java,
__init__(self) is not a constructor! The initializer is responsible for initializing the instance variables, which we'll talk more about in a moment.
We rarely need to actually to define our own constructor. If you really know what you're doing, you can redefine the
__new__(cls) function...
def __new__(cls): return object.__new__(cls)
By the way, if you're looking for the destructor, that's the
__del__(self) function.
Variables
In Python, our classes can have instance variables, which are unique to our object (instance), and class variables (a.k.a. static variables), which belong to the class, and are shared between all instances.
I have a confession to make: I spent the first few years of Python development doing this absolutely and completely wrong! Coming from other object-oriented languages, I actually thought I was supposed to do this:
class Starship(object): engines = False engine_speed = 0 shields = True def __init__(self): self.engines = False self.engine_speed = 0 self.shields = True def engage(self): self.engines = True def warp(self, factor): self.engine_speed = 2 self.engine_speed *= factor
The code works, so what's wrong with this picture? Read it again, and see if you can figure out what's happening.
Final Jeopardy music plays
Maybe this will make it obvious.
uss_enterprise = Starship() uss_enterprise.warp(4) print(uss_enterprise.engine_speed) >>> 8 print(Starship.engine_speed) >>> 0
Did you spot it?
Class variables are declared outside of all functions, usually at the top. Instance variables, on the other hand, are declared in the
__init__(self) function: for example,
self.engine_speed = 0.
So, in our little example, we've declared a set of class variables, and a set of instance variables, with the same names. When accessing a variable on the object, the instance variables shadow (hide) the class variables, making it behave as we might expect. However, we can see by printing
Starship.engine_speed that we have a separate class variable sitting in the class, just taking up space. Talk about redundant.
Anyone get that right? Sloan did, and wagered...ten thousand cecropia leaves. Looks like the sloth is in the lead. Amazingly enough.
By the way, you can declare instance variables for the first time from within any instance method, instead of the initializer. However...you guessed it: don't. The convention is to ALWAYS declare all your instance variables in the initializer, just to prevent something weird from happening, like a function attempting to access a variable that doesn't yet exist.
Scope: Private and Public
If you come from another object-oriented language, such as Java and C++, you're also probably in the habit of thinking about scope (private, protected, public) and its traditional assumptions: variables should be private, and functions should (usually) be public. Getters and setters rule the day!
I'm also an expert in C++ object-oriented programming, and I have to say that I consider Python's approach to the issue of scope to be vastly superior to the typical object-oriented scope rules. Once you grasp how to design classes in Python, the principles will probably leak into your standard practice in other languages...and I firmly believe that's a good thing.
Ready for this? Your variables don't actually need to be private.
Yes, I just heard the gurgling scream of the Java nerd in the back. "But...but...how will I keep developers from just tampering with any of the object's instance variables?"
Often, that concern is built on three flawed assumptions. Let's set those right first:
The developer using your class almost certainly isn't in the habit of modifying member variables directly, any more than they're in the habit of sticking a fork in a toaster.
If they do stick a fork in the toaster, proverbially speaking, the consequences are on them for being idiots, not on you.
As my Freenode #python friend
grymonce said, "if you know why you aren't supposed to remove stuck toast from the toaster with a metal object, you're allowed to do so."
In other words, the developer who is using your class probably knows better than you do about whether they should twiddle the instance variables or not.
Now, with that out of the way, we approach an important premise in Python: there is no actual 'private' scope. We can't just stick a fancy little keyword in front of a variable to make it private.
What we can do is stick an underscore at the front of the name, like this:
self._engine.
That underscore isn't magical. It's just a warning label to anyone using your class: "I recommend you don't mess with this. I'm doing something special with it."
Now, before you go sticking
_ at the start of all your instance variable names, think about what the variable actually is, and how you use it. Will directly tweaking it really cause problems? In the case of our example class, as it's written right now, no. This actually would be perfectly acceptable:
uss_enterprise.engine_speed = 6 uss_enterprise.engage()
Also, notice something beautiful about that? We didn't write a single getter or setter! In any language, if a getter or setter are functionally identical to modifying the variable directly, they're an absolute waste. That philosophy is one of the reasons Python is such a clean language.
You can also use this naming convention with methods you don't intend to be used outside of the class.
Side Note: Before you run off and go eschew
private and
protected from your Java and C++ code, please understand that there's a time and a place for scope. The underscore convention is a social contract among Python developers, and most languages don't have anything like that. So, if you're in a language with scope, use
private or
protected on any variable you would have put an underscore in front of in Python.
Private...Sort Of
Now, on a very rare occasion, you may have an instance variable which absolutely, positively, never, ever should be directly modified outside of the class. In that case, you may precede the name of the variable with two underscores (
__), instead of one.
This doesn't actually make it private; rather, it performs something called name mangling: it changes the name of the variable, adding a single underscore and the name of the class on the front.
In the case of
class Starship, if we were to change
self.shields to
self.__shields, it would be name mangled to
self._Starship__shields.
So, if you know how that name mangling works, you can still access it...
uss_enterprise = Starship() uss_enterprise._Starship__shields >>> True
It's important to note, you also cannot have more than one trailing underscore if this is to work. (
__foo and
__foo_ will be mangled, but
__foo__ will not). But then, PEP 8 generally discourages trailing underscores, so it's kinda a moot point.
By the way, the purpose of the double underscore (
__) name mangling actually has nothing to do with private scope; it's all about preventing name conflicts with some technical scenarios. In fact, you'll probably get a few serious frowns from Python ninjas for employing
__ at all, so use it sparingly.
Properties
As I said earlier, getters and setters are usually pointless. On occasion, however, they have a purpose. In Python, we can use properties in this manner, as well as to pull off some pretty nifty tricks!
Properties are defined simply by preceding a method with
@property.
My favorite trick with properties is to make a method look like an instance variable...
class Starship(object): def __init__(self): self.engines = True self.engine_speed = 0 self.shields = True @property def engine_strain(self): if not self.engines: return 0 elif self.shields: # Imagine shields double the engine strain return self.engine_speed * 2 # Otherwise, the engine strain is the same as the speed return self.engine_speed
When we're using this class, we can treat
engine_strain as an instance variable of the object.
uss_enterprise = Starship() uss_enterprise.engine_strain >>> 0
Beautiful, isn't it?
(Un)fortunately, we cannot modify
engine_strain in the same manner.
uss_enterprise.engine_strain = 10 >>> Traceback (most recent call last): >>> File "<stdin>", line 1, in <module> >>> AttributeError: can't set attribute
In this case, that actually does make sense, but it might not be what you're wanting other times. Just for fun, let's define a setter for our property too; at least one with nicer output than that scary error.
@engine_strain.setter def engine_strain(self, value): print("I'm giving her all she's got, Captain!")
We precede our method with the decorator
@NAME_OF_PROPERTY.setter. We also have to accept a single
value argument (after
self, of course), and positively nothing beyond that. You'll notice we're not actually doing anything with the
value argument in this case, and that's fine for our example.
uss_enterprise.engine_strain = 10 >>> I'm giving her all she's got, Captain!
That's much better.
As I mentioned earlier, we can use these as getters and setters for our instance variables. Here's a quick example of how:
class Starship: def __init__(self): # snip self._captain = "Jean-Luc Picard" @property def captain(self): return self._captain @captain.setter def captain(self, value): print("What do you think this is, " + value + ", the USS Pegasus? Back to work!")
We simply preceded the variable these functions concern with an underscore, to indicate to others that we intend to manage the variable ourselves. The getter is pretty dull and obvious, and is only needed to provide expected behavior. The setter is where things are interesting: we knock down any attempted mutinies. There will be no changing this captain!
uss_enterprise = Starship() uss_enterprise.captain >>> 'Jean-Luc Picard' uss_enterprise.>> What do you think this is, Wesley, the USS Pegasus? Back to work!
Technical rabbit trail: if you want to create class properties, that requires some hacking on your part. There are several solutions floating around the net, so if you need this, go research it!
A few of the Python nerds will be on me if I didn't point out, there is another way to create a property without the use of decorators. So, just for the record, this works too...
class Starship: def __init__(self): # snip self._captain = "Jean-Luc Picard" def get_captain(self): return self._captain def set_captain(self, value): print("What do you think this is, " + value + ", the USS Pegasus? Back to work!") captain = property(get_captain, set_captain)
(Yes, that last line exists outside of any function.)
As usual, the documentation on properties has additional information, and some more nifty tricks with properties.
Inheritance
Finally, we come back to that first line for another look.
class Starship(object):
Remember why that
(object) is there? We're inheriting from Python's
object class. Ahh, inheritance! That's where it belongs.
class USSDiscovery(Starship): def __init__(self): super().__init__() self.spore_drive = True self._captain = "Gabriel Lorca"
The only real mystery here is that
super().__init__() line. In short,
super() refers to the class we inherited from (in this case,
Starship), and calls its initializer. We need to call this, so
USSDiscovery has all the same instance variables as
Starship.
Of course, we can define new instance variables (
self.spore_drive), and redefine inherited ones (
self._captain).
We could have actually just called that initializer with
Starship.__init__(), but then if we wanted to change what we inherit from, we'd have to change that line too. The
super().__init__() approach is ultimately just cleaner and more maintainable.
Legacy Note: By the way, if you're using Python 2, that line is a little uglier:
super(USSDiscovery, self).__init__().
Before you ask: YES, you can do multiple inheritance with
class C(A, B):. It actually works better than in most languages! Regardless, but you can count on a side order of headaches, especially when using
super().
Hold the Classes!
As you can see, Python classes are a little different from other languages, but once you're used to them, they're actually a bit easier to work with.
But if you've coded in class-heavy languages like C++ or Java, and are working on the assumption that you need classes in Python, I have a surprise for you. You really aren't required to use classes at all!
Classes and objects have exactly one purpose in Python: data encapsulation. If you need to keep data and the functions for manipulating it together in a handy unit, classes are the way to go. Otherwise, don't bother! There's absolutely nothing wrong with a module composed entirely of functions.
Review
Whew! You still with me? How many of those surprises about classes in Python did you guess?
Let's review...
The
__init__(self)function is the initializer, and that's where we do all of our variable initialization.
Methods (member functions) must take
selfas their first argument.
Class methods must take
clsas their first argument, and have the decorator
@classmethodon the line just above the function definition. They can access class variables, but not instance variables.
Static methods are similar to class methods, except they don't take
clsas their first argument, and are preceded by the decorator
@staticmethod. They cannot access any class or instance variables or functions. They don't even know they're part of a class.
Instance variables (member variables) should be declared inside
__init__(self)first. We don't declare them outside of the constructor, unlike most other object-oriented languages.
Class variables or static variables are declared outside of any function, and are shared between all instances of the class.
There are no private members in Python! Precede a member variable or a method name with an underscore (
_) to tell developers they shouldn't mess with it.
If you precede a member variable or method name with two underscores (
__), Python will change its name using name mangling. This is more for preventing name conflicts than hiding things.
You can make any method into a property (it looks like a member variable) by putting the decorator
@propertyon the line above its declaration. This can also be used to create getters.
You can create a setter for a property (e.g.
foo) by putting the decorator
@foo.setterabove a function
foo.
A class (e.g.
Dog) can inherit from another class (e.g.
Animal) in this manner:
class Dog(Animal):. When you do this, you should also start your initializer with the line
super().__init__()to call the initializer of the base class.
Multiple inheritance is possible, but it might give you nightmares. Handle with tongs.
As usual, I recommend you read the docs for more:
- Python Tutorials: Classes
- Python Reference: Built-In Functions - @classmethod
- Python Reference: Built-In Functions - @staticmethod
- Python Reference: Built-In Functions - @property

Discussion
I read a really funny analogy for why python’s private-ish variables are good enough and we don’t have stricter access control:
Thanks for the article!
I'd like to add that you should mention that there's pretty much never a good reason to use
staticmethodas opposed to a global method in the module.
Usually, when we write a module, we can simply write a method outside the class, to get the same behaviour as a
staticmethod
I try to avoid such statements, especially in this article series. If it exists, it exists for some reason. ;)
That said, I plan to discuss the ins and outs of this in more depth in the book.
Ah I see! I really appreciate this series. It is very well written and enjoyable to read!
By the way, what is that reason?
Namespacing.
Thanks for the excellent Article.
Some small suggestion: in the
setterexample the actual line of code that sets the Instance Member
self.__captain = valueis missing ;-)
Resulting in this output, Jean-Luc Picard refuses to go away....
Awesome coverage of classes in Python! Kudos to showing how to set properties using getters/setters. When I first learned python, I did not understand this and would create my own def to modify a property on my instances. Very fun, Next Generation is my favorite Trek series.
Should
clsbe passed into a staticmethod? I thought that was only for class methods
I cannot believe it! I actually missed that little detail:
@staticmethodand
@classmethodare actually two separate things!
I've just edited the article to correct that, and added a new section to clarify the difference. Thank you so much for correcting that.
Great article!
Nice, properties, getters, and setters all explain some things I had never even seen or thought of before (Python being my first programming language), it definitely expanded my understanding of what a class is and can do.
Great article! Python is neither my primary nor my secondary language, but I've been using it a lot for my grad school work. I realize how naive my own Python code has been after reading your post haha. Do you have any suggestions for more material like this to learn the best practices? I have found that the python docs are not the most captivating. Thank you for this post! Great job.
Unfortunately, I haven't found much! That's precisely why I started this article series.
If you have some extra cash laying around, you could sign up for Udemy: The Complete Python Course by Codestars. He covers good practice pretty well. However, it is unfortunately quite beginner-oriented, so it's slow going at first.
in the subtopic Methods should be
as engage has no parameter factor
Another great catch. Thank you!
In inheritance, what if we do not write 'super().init()' in child class' init() method? Does child class not call it by default?
No, it doesn't, as far as I know. As mentioned in the Zen of Python,
Explicit is better than implicit. It's part of the language philosophy.
We often need to handle passing data to the parent
__init__()in a specific way, and we may need to do some other things first, so Python just assumes we know best how to handle that.
Imagine how maddening it could get if Python sometimes called it for you, but sometimes not! (Some languages actually are confusing like that, but Python aims to be obvious.)
Thanks for clarifying!
It would be very helpful if you also explain MRO (Method Resolution Order) in context of Python 3 in any upcoming series.
This was a very clear and well-written article, probably one of the best that I’ve read regarding Python classes. Thanks!
Nice article Jason. Keep writing more.
Thanks for writing this article.Jason
Thank you for great article!
Just one thing, you have a typo in your example "engine_strain" as @property. It should be "elif" instead "else if".
Thanks for catching that!
Not quite. The class variables are shadowed; instance variables eclipse, as they dominate.
Good article, thanks 😎 | https://dev.to/codemouse92/dead-simple-python-classes-42f7 | CC-MAIN-2020-40 | en | refinedweb |
How to link with Apple Frameworks¶
It is common in MacOS that your Conan package needs to link with a complete Apple framework, and, of course, you want to propagate this information to all projects/libraries that use your package.
With regular libraries, use
self.cpp_info.libs object to append to it all the libraries:
def package_info(self): self.cpp_info.libs = ["SDL2"] self.cpp_info.libs.append("OpenGL32")
With frameworks we need to use
self.cpp_info.frameworks in a similar manner:

future.scala is the spiritual successor to Stateless Future for stack-safe asynchronous programming in pure functional flavor. We dropped the Stateless Future's built-in
async/
await support, in favor of more general
monadic/
each syntax provided by ThoughtWorks Each.
future.scala provide an API similar to
scala.concurrent.Future or
scalaz.concurrent.Task, except future.scala does not throw the
StackOverflowError.
DesignDesign
future.scala inherits many design decision from Stateless Future.
StatelessnessStatelessness
future.scala are pure functional, thus they will never store result values or exceptions. Instead, future.scala evaluate lazily, and they do the same job every time you invoke
onComplete.
Also, there is no
isComplete method in our futures. As a result, the users of future.scala are forced not to share futures between threads, not to check the states in futures. They have to care about control flows instead of threads, and build the control flows by creating futures.
Threading-free ModelThreading-free Model
There are too many threading models and implementations in the Java/Scala world,
java.util.concurrent.Executor,
scala.concurrent.ExecutionContext,
javax.swing.SwingUtilities.invokeLater,
java.util.Timer, ... It is very hard to communicate between threading models. When a developer is working with multiple threading models, he must very carefully pass messages between threading models, or he have to maintain bulks of
synchronized methods to properly deal with the shared variables between threads.
Why does he need multiple threading models? Because the libraries that he uses depend on different threading modes. For example, you must update Swing components in the Swing's UI thread, you must specify
java.util.concurrent.ExecutionServices for
java.nio.channels.CompletionHandler, and, you must specify
scala.concurrent.ExecutionContexts for
scala.concurrent.Future and
scala.async.Async. Oops!
Think about somebody who uses Swing to develop a text editor software. He wants to create a state machine to update UI. He have heard the cool
scala.async, then he uses the cool "A-Normal Form" expression in
async to build the state machine that updates UI, and he types
import scala.concurrent.ExecutionContext.Implicits._ to suppress the compiler errors. Everything looks pretty, except the software always crashes.
Fortunately, future.scala depends on none of these threading model, and cooperates with all of these threading models. If the poor guy tries future.scala, replacing
async { } to
monadic[Future] { }, deleting the
import scala.concurrent.ExecutionContext.Implicits._, he will find that everything looks pretty like before, and does not crash any more. That's why threading-free model is important.
Exception HandlingException Handling
There were two
Future implementations in Scala standard library,
scala.actors.Future and
scala.concurrent.Future.
scala.actors.Futures are not designed to handling exceptions, since exceptions are always handled by actors. There is no way to handle a particular exception in a particular subrange of an actor.
Unlike
scala.actors.Futures,
scala.concurrent.Futures are designed to handle exceptions. Unfortunately,
scala.concurrent.Futures provide too many mechanisms to handle an exception. For example:
import scala.concurrent.Await import scala.concurrent.ExecutionContext import scala.concurrent.duration.Duration import scala.util.control.Exception.Catcher import scala.concurrent.forkjoin.ForkJoinPool val threadPool = new ForkJoinPool() val catcher1: Catcher[Unit] = { case e: Exception => println("catcher1") } val catcher2: Catcher[Unit] = { case e: java.io.IOException => println("catcher2") case other: Exception => throw new RuntimeException(other) } val catcher3: Catcher[Unit] = { case e: java.io.IOException => println("catcher3") case other: Exception => throw new RuntimeException(other) } val catcher4: Catcher[Unit] = { case e: Exception => println("catcher4") } val catcher5: Catcher[Unit] = { case e: Exception => println("catcher5") } val catcher6: Catcher[Unit] = { case e: Exception => println("catcher6") } val catcher7: Catcher[Unit] = { case e: Exception => println("catcher7") } def future1 = scala.concurrent.future { 1 }(ExecutionContext.fromExecutor(threadPool, catcher1)) def future2 = scala.concurrent.Future.failed(new Exception) val composedFuture = future1.flatMap { _ => future2 }(ExecutionContext.fromExecutor(threadPool, catcher2)) composedFuture.onFailure(catcher3)(ExecutionContext.fromExecutor(threadPool, catcher4)) composedFuture.onFailure(catcher5)(ExecutionContext.fromExecutor(threadPool, catcher6)) try { Await.result(composedFuture, Duration.Inf) } catch { case e if catcher7.isDefinedAt(e) => catcher7(e) }
Is any sane developer able to tell which catchers will receive the exceptions?
There are too many concepts about exceptions when you work with
scala.concurrent.Future. You have to remember the different exception handling strategies between
flatMap,
recover,
recoverWith and
onFailure, and the difference between
scala.concurrent.Future.failed(new Exception) and
scala.concurrent.future { throw new Exception }.
scala.async does not make things better, because
scala.async will produce a compiler error for every
await in a
try statement.
Fortunately, you can get rid of all those concepts if you switch to future.scala. There is neither
executor implicit parameter in
flatMap or
map in future.scala, nor
onFailure nor
recover method at all. You just simply
try, and things get done. See the examples to learn that.
Tail Call OptimizationTail Call Optimization
Tail call optimization is an important feature for pure functional programming. Without tail call optimization, many recursive algorithm will fail at run-time, and you will get the well-known
StackOverflowError.
future.scala project is internally based on
scalaz.Trampoline, and automatically performs tail call optimization in the
monadic[com.thoughtworks.future.Future] { ??? } blocks, without any additional special syntax.
Here is a trivial example:
import scalaz.syntax.all._ import com.thoughtworks.raii.asynchronous._ import com.thoughtworks.continuation._ def v: UnitContinuation[Unit] = UnitContinuation.now(Unit) def f(x: Int): UnitContinuation[Unit] = v.flatMap { _ => g(x+1) } def g(x: Int): UnitContinuation[Unit] = v.flatMap { _ => f(x+1) }
Calling
f(0).blockingAwait results in an infinite loop without stack overflow. Mutually recursive calls are also fine in this case, as long as the calls are tail calls.
See this example. The example creates 30000 stack levels recursively. And it just works, without any
StackOverflowError or
OutOfMemoryError. Note that if you port this example for
scala.async it will throw an
OutOfMemoryError or a
TimeoutException.

Hi, I always had problems with sorting the completion result elements, could you point in the right direction direction for doing this?
I have an extension point for "completion.contributor", I'm adding my LookupElements to the result and that works fine, but I want to show my elements on top, is this possible?
I've tried adding an extension point for "weigher", and I'm using a code like this:
public class MagicentoPhpWeigher extends CompletionWeigher {
@Override
public Integer weigh(@NotNull LookupElement element, @NotNull CompletionLocation location)
{
if (location == null) {
return null;
}
Object object = element.getObject(); // we can pass any object inside the LookupElement creator in our MagicentoXmlCompletionContributor
if(object instanceof String){
String reference = (String) object;
if(reference.startsWith("magicento")){
return -100;
}
}
return null;
}
}
for some strange reason this was working fine in PHPStorm 5, but not in v6
Thanks !
Enrique.
When you add your LookupElement to the CompletionResultSet, you could use such an approach
to give your element different importance level. I struggled with the CompletionWeighter implementation too until I
found this and therefore, I would be intereste in a propper way too.
I've tried that but I'm getting weird results, I have a code like this:
For example:
Ctrl+Space (first time):
Ctrl+Space (second time):
Is this the normal/expected behavior?
It doesn't seem to be normal. Are all elements in the list added by your contributor? Does the list appear quickly, or shows calculation progress for some time?
I think this is solved now just adding "order=first" to my contributor | https://intellij-support.jetbrains.com/hc/en-us/community/posts/206772715-Sort-Completion-Result-elements?sort_by=created_at | CC-MAIN-2020-40 | en | refinedweb |
Asked by:
Domain Object Model and the Law of Demeter.
Question
Hey folks, first of all thanks everyenu for contributing to my last question; not sure how to mark it off except to make it a discussion. Thanks though. Helped a lot.
Another issue has raised it's head and this always seems to come about when I develop and the clue is in the posts title. Here is the situation.
I create an object model, usually a hierarchy of object with a top level root object going down levels into child object that themselves have child objects. Here is a small example from my current project.
public class Input
{
public ProjectInformation ProjectInformation { get; set; }
public Options Options { get; set; }
public Plant Plant { get; set; }
public Load DesignLoad
{
get { return this.loads.Where(load => load.IsDesignLoad).First(); }
}
Ok so you can see the Input class, the root object, is made up of other child classes ProjectInformation, Options, Plant and Load. Ok lets look at some of the Load class.
public class Load
{
public string Name { get; set; }
public Fuel Fuel { get; set; }
public CombustionHeat CombustionHeat { get; set; }
public CombustionAir CombustionAir { get; set; }
Ok the Load class is made up some other child objects Fuel, Heat, and Air. Lets look at the Fuel class.....
public class Fuel
{
public Coal Coal { get; set; }
public Gas Gas { get; set; }
public Oil Oil { get; set; }
... ok so you seeing the idea...
If you have any immediate comments about this design approach them let me know. Most of the software I write tends ta have this sort of tree of objects and if it's wrong or if there is a better way then please please let me know.
Ok so I have this tree of objects that represents Input and this is where the information comes from when doing processing... calculations...
What I'm finding, and it tends to happen, is I write code like this....
double[] airFlowRatesExc = input.DesignLoad.AirFlow;
double[] coalFlowRates = input.DesignLoad.Fuel.Coal.FlowRates.PARate;
See the train crash?!
Law of Demeter does not apply and I have a horrible feeling it's going to bite me some day in the not to distant future.
The last thing I want to do is have a host of methods on the root Input object that return data from the lowest level in the object tree, well I say the last thing but what I mean by that is if there was an easy way to do it then I would but ... I'm sure you know what I'm getting at.
What's going through your mind right now reading this?
What's your opinion of creating the tree of objects like that? in there an alternative, or a suitable alternative approach that you would recommend and have used?
How about the law of demeter; is it a law?
Anything you have to say folks.

All replies
You seem to have a lot of levels there mate.
Why is there an input class at all?
Next thought is why are your calculations carried out way up there in the top class.
Are these objects you have there really objects or are they just classifications of input?
Could you just have regions rather than classes for some of them?
I tend to apply the rule of 4 effs.
That's the four fan fold fingers rule.
It dates back to when I used to work in cobol and read fan fold printouts.
Going down a level to a different procedure ( object/class) I'd stick a finger in the fan fold where I was going from.
About the time I ran out of fingers I'd have completely lost track of all the levels I had come down to get wherever I was.
Not a hard and fast rule but something to consider.
Hey Andy, thanks for your post.
Yeah there are a few child levels in the object tree.
Been thinking of what you posted about whether the classes that are listed are regions or classes and for some places they could be considered regions. ProjectInformation and Configuration are not real work objects and yeah could be considered more of a classification / region. Well ... configuration could be real world, the configuration of the thing. But most of the classes in the code are real world objects or represent real world things and their relationships.
For example Fuel is a real tangable thing in they system and it's composed of a mixture of Coal, Oil and Gas, which themselves are real things.
The more I think of it the more it makes sense; the other option would be to flatten the tree into a collection of dictionaries. That would work and would have been nice but I'd lose a certain amount of type safety. Everything in the dictionary approach would be of type object.
Your absolutely right though the deep level in the object tree is what's conflicting with the law of demeter and causing the train crash code.
So I've been thinking how can the tree remain, because it feels accurate, with the deep levels but be accessed like things were flat. The visitors design pattern!
What this has done is seperated out the processing that's done on the tree from the structure of the tree. It works very well and provides a lot of options in adding new features without worrying to much about the impact of structural changes to the tree. Well to a degree. The visitor pattern treats each type of object in the tree as seperate from other types of objects. It's not perfect but think I'll go with it.

Outlier treatment and Featuring Engineering would be the next steps in continuation to Missing Data Treatment.
Outliers Definition:
An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. It is an observation that deviates from overall pattern on a sample.
Outliers can be caused due to multiple reasons like:
- Data Entry Errors
- Intermediate Data processing Errors
- Instrument recording errors
- Natural Error or which does not denote an error
Outlier Detection and Treatment:
Outliers can be Univariate or Multivariate meaning on single feature or collection of features respectively. Boxplots or Scatter plots are an easy way of determining the outliers in a sample. Interquartile Range is most commonly used technique to determine an outlier. Below is an example to understand the same:
Sample: 4, 7, 9, 11, 12, 20 (arranged in ascending order)
Divide sample into 2 so lower half is 4, 7, 9 and upper half is 11, 12, 20
Find Median of lower and upper half which is 7 and 12 respectively
So Q1 = 7 and Q3 = 12
IQR = Q3 – Q1 which is 5 (12 -7 = 5)
Outliers: a = Q1 – (1.5*IQR); b = Q3 = Q1 – (1.5*IQR)
any number < a or > b is an outlier.
Hence in our sample 20 is an outlier.
Outlier Treatment:
One way of getting rid outliers is by removing them observation (or deleting the row). But by doing so we might reduce the size of the sample or dataset which will not help in modelling.
Another most commonly used technique is using transformation or binning the variable. Transformation is by taking the natural log of the value which greatly reduces the variation specially used when we have too extreme values. Binning as the name suggests classifying all the values into set of defined bins (like 0-10; 10-20; 20-30 and so on..)
Feature Engineering:
This is an art of extracting more meaningful information from the existing data without adding anything new. In housing data, having total Sq. Feet is more relevant than having individual floor Square Feet which can be considered as Feature Engineering.
Feature Engineering process should be performed after completing Exploratory Data Analysis (EDA), Missing value treatment and Outlier treatment.
Now we will see it in action using the same Ames housing data set. I will be using the output of my missing value treatment script discussed in another post. You can find the script here .
Import Libraries:
import pandas as pd import numpy as np import matplotlib.pyplot as plt %matplotlib inline from matplotlib import rcParams rcParams['figure.figsize'] = 12,10 import seaborn as sb
Read Dataset:
df = pd.read_csv('C:/../Ames_cleaned.csv') df.shape
(2919, 70)
Let us try to find outliers in continuous variables like:
‘1stFlrSF’,’2ndFlrSF’,’TotalBsmtSF’
sb.boxplot(x=df[['1stFlrSF','2ndFlrSF','TotalBsmtSF']])
Clearly we can see there are some extreme values for 1stFlrSF and TotalBsmtSF. However we will not do an outlier treatment now because we will do some Feature Engineering to them. We will combine all of them as TotalSF and see how the boxplot shows up.
#Feature Engineering df['TotalSF'] = df['1stFlrSF'] + df['2ndFlrSF'] + df['TotalBsmtSF'] sb.boxplot(x=df['TotalSF'], orient='v')
Now lets see for SalePrice, GrLivArea and LotFrontage
sb.boxplot(x=df['GrLivArea'], orient='v') plt.show() sb.boxplot(x=df['LotFrontage'], orient='v') plt.show() sb.boxplot(x=df['LotFrontage'], orient='v')
Clearly there are some extreme outliers in the data. We will use log transformation to reduce the variation which means the outliers will be removed completely but extreme values become reasonably better.
Log transforming TotalSF, GrLivArea, LotFrontage
#Log transforming df['GrLivArea'] = np.log(df['GrLivArea']) df['LotFrontage'] = np.log(df['LotFrontage']) df['TotalSF'] = np.log(df['TotalSF']) #plotting after transformation sb.boxplot(x=df['GrLivArea'], orient='v') plt.show() sb.boxplot(x=df['LotFrontage'], orient='v') plt.show() sb.boxplot(x=df['TotalSF'], orient='v')
It is evident from the above graphs that extreme outliers are treated.
We can combine BedroomAbvGr and TotRmsAbvGrd into TotalRooms.
Following that we will drop all the variables which were feature engineered
df['TotalRooms'] = df['BedroomAbvGr'] + df['TotRmsAbvGrd'] # Drop Feature engineered columns col_fe = ['1stFlrSF','2ndFlrSF','BsmtFinSF1','BsmtFinSF2','BsmtUnfSF','TotalBsmtSF','BedroomAbvGr','TotRmsAbvGrd'] df.drop(col_fe, axis=1, inplace=True) print('Total Features after removing engineered features: ', (df.shape))
Total Features after removing engineered features: (2919, 64)
Split into train and test datasets
train = df.loc[df['source'] == 'train'] test = df.loc[df['source'] == 'test'] print(train.shape, test.shape)
(1460, 64) (1459, 64)
For categorical variables we will try to find the percentage of most frequent value. In other words percentage of mode.
We will drop the variables which have mode > 80%. This is because there is very less variability and hence might not have significant contribution to the model.
# Drop columns which have frequency of value more than 80% of all values col, axis=1, inplace=True) print('Total features after dropping categorical features: ', df.shape)
Total features after dropping categorical features: (2919, 44)
With this we have tried to understand some basics on Outlier Treatment and Feature Engineering. Feature Engineering is the most critical step which determines the success of the model. Hence an in-depth understanding of the domain of the dataset is a huge advantage to derive relevant features necessary for building a Predictive Model.

1 Introduction
FriendlyThings is an Android SDK developed by FriendlyElec to access hardware. Users can use it to access various hardware resources Uart, SPI, I2C, GPIO etc on a FriendlyElec ARM board under Android. This SDK is based on Android-NDK. Users can use it to develop popular IoT applications without directly interacting with drivers.
2 Android Versions
The Android BSPs provided by FriendlyElec already have FriendlyThings SDK(libfriendlyarm-things.so) and currently have two version:
- Android 7.1.2-rk3399
BSP source code download link:

3 List of Applicable Boards
FriendlyThings SDK(libfriendlyarm-things.so) works with the following FriendlyElec RK3399 based boards:
- NanoPC-T4
- NanoPi M4 (an external eMMC module is needed)
- NanoPi NEO4 (an external eMMC module is needed)
FriendlyThings might also work with other FriendlyElec boards such as Samsung S5P4418/S5P6818, Samsung S5PV210, Allwinner H3/H5 etc. For more details refer to FriendlyThings
4 Quick Start
4.1 Step 1: Include libfriendlyarm-things.so in APP
Clone the following library locally:
git clone
Copy all the files under the libs directory to your working directory and create a "com/friendlyarm" directory in your Android project's src directory, copy the whole "java/FriendlyThings" to your newly created "com/friendlyarm" directory. The whole project directory will look like this(Note:AndroidStudio's project may be a little bit different):
YourProject/ ├── AndroidManifest.xml ├── libs │ ├── arm64-v8a │ │ └── libfriendlyarm-things.so │ └── armeabi │ └── libfriendlyarm-things.so ├── src │ └── com │ └── friendlyarm │ ├── FriendlyThings │ │ ├── BoardType.java │ │ ├── FileCtlEnum.java │ │ ├── GPIOEnum.java │ │ ├── HardwareControler.java │ │ ├── SPIEnum.java │ │ ├── SPI.java │ │ └── WatchDogEnum.java
Import the following components and the major APIs are included in the HardwareControler.java file:
import com.friendlyarm.FriendlyThings.HardwareControler; import com.friendlyarm.FriendlyThings.SPIEnum; import com.friendlyarm.FriendlyThings.GPIOEnum; import com.friendlyarm.FriendlyThings.FileCtlEnum; import com.friendlyarm.FriendlyThings.BoardType;
4.2 Step 2: Give APP System Right
Your app needs the system right to access hardware resources;
Give your app the system right by making changes in the AndroidManifest.xml file and the Android.mk file;
It is better to include your app in your Android source code and compile them together. If your app is not compiled together with your Android source code you have to go through tedious steps to compile your app and sign your app to give it the system right.
4.2.1 Modify AndroidManifest.xml
Add the following line in the manifest node in the AndroidManifest.xml file:
android:sharedUserId="android.uid.system"
4.2.2 Modify Android.mk
Create an Android.mk file(the simplest way is to copy a sample Android.mk file), modify the Android.mk file by adding a line LOCAL_CERTIFICATE := platform :
LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) LOCAL_SRC_FILES := $(call all-subdir-java-files) LOCAL_PACKAGE_NAME := Project Name LOCAL_CERTIFICATE := platform LOCAL_MODULE_TAGS := optional LOCAL_CFLAGS := -lfriendlyarm-hardware include $(BUILD_PACKAGE)
4.3 Final Step: Compile Your APP Together with Android Source Code
Go to Android source code's root directory and run "setenv.sh" to export environmental variables, enter your app's directory and run "mm" to compile:
For example: compile the GPIO_LED_Demo on RK3399:
cd rk3399-android-8.1 . setenv.sh cd vendor/friendlyelec/apps/GPIO_LED_Demo mm
5 APIs in libfriendlyarm-things.so Library
Refer to this wiki site:FriendlyThings APIs
6 Access RK3399 Based Boards' Hardware under Android
6.1 Serial Port
Currently the only available serial port for users is UART4 and its device name is "/dev/ttyS4". Other serial ports are already taken. Here is a list of the serial ports and their functions. If you need more serial ports you can convert USB ports to serial ports:
6.1.1 APIs for Accessing Serial Ports
HardwareControler.openSerialPortEx //opens a serial port. HardwareControler.select //polls a serial port's status and checks if it has data to be read or if data can be written to it. HardwareControler.read //reads data from a serial port. HardwareControler.write //writes data to a serial port. HardwareControler.close //closes a serial port.
For more details refer to :FriendlyThings APIs
6.2 GPIO
You can access GPIO by calling sysfs APIs. You need to access the "/sys/class/gpio" directory, write a GPIO index number you want to access to the export file, and set the GPIO's direction and value.
Here is a list of GPIOs FriendlyElec's RK3399 boards support:
- NanoPC T4
- NanoPi M4和NanoPi NEO4
6.2.1 APIs for Accessing GPIO
HardwareControler.exportGPIOPin //exports a GPIO. HardwareControler.setGPIODirection //sets a GPIO's direction. HardwareControler.getGPIODirection //gets a GPIO's direction. HardwareControler.setGPIOValue //sets a GPIO's value. HardwareControler.getGPIOValue //gets a GPIO's value HardwareControler.unexportGPIOPin //unexports a GPIO.
For more details refer to:FriendlyThings APIs
6.2.2 Testing GPIO
You can use a FriendlyElec's LED module to test GPIOs. Set a HIGH to turn on the LED and a LOW to turn off the LED.
6.3 ADC
RK3399 populates three ADC channels 0, 2 and 3 and here is a list of the channels and their corresponding nodes:
You can access GPIOs like accessing files under Android.
6.4 PWM
Note: The PWM interface is already used by the fan by default. If you want to control the PWM by yourself, you need to disable the fan first,
Please refer to: Template:RK3399 Android PWMFan
You can access PWMs by calling sysfs APIs. You can access the nodes under the "/sys/class/pwm/pwmchip1" directory. Here is code sample to control a PWM fan:
6.4.1 APIs for Accessing PWM
- Export PWM0 to users
echo 0 > /sys/class/pwm/pwmchip1/export
- Control a PWM fan's speed by setting the PWM's period and duty_cycle.
6.4.2 Testing PWM
Connect a PWM fan(3 pins) to a NanoPC-T4's fan port to test it.
6.5 I2C
To test I2C we connected a FriendlyElec's LCD1602 module to a NanoPC-T4 and ran the I2C demo program:
Here is a hardware setting:
6.6 RTC
You can access RTC by calling APIs under the "/sys/class/rtc/rtc0/" directory. For instance you can check the current RTC time by running the following commands:
cat /sys/class/rtc/rtc0/date # 2018-10-20 cat /sys/class/rtc/rtc0/time # 08:20:14
Set power-on time. For instance power on in 120 seconds:

6.7 Watch dog
It is quite straightforward to access the watch dog. You can simply open the "/dev/watchdog" device and write characters to it.If for any reason no characters can be written to the device the system will reboot in a moment:
mWatchDogFD = HardwareControler.open("/dev/watchdog", FileCtlEnum.O_WRONLY); HardwareControler.write(mWatchDogFD, "a".getBytes());
6.8 SPI
6.8.1 Enable SPI
The SPI and UART4 share the same pins. You need to modify the kernel's DTS file to enable the SPI by running the following commands:
Edit the DTS file: arch/arm64/boot/dts/rockchip/rk3399-nanopi4-common.dtsi:
cd ANDROID_SOURCE/kernel vim arch/arm64/boot/dts/rockchip/rk3399-nanopi4-common.dtsi
You need to replace "ANDROID_SOURCE" to your real source. In our system it is either Android7's or Android8's source code directory.
Locate spi1's definition:
&spi1 { status = "disabled"; // change "disabled" to "okay"
Locate uart4's definition in the rk3399-nanopi4-common.dtsi file:
&uart4 { status = "okay"; // change "okay" to "disabled"
Compile kernel:
cd ANDROID_SOURCE/ ./build-nanopc-t4.sh -K -M
Use the newly generated "rockdev/Image-nanopc_t4/resource.img" image file to update your system.
6.8.2 Testing SPI
By default the SPI is not enabled in your system. You need to manually enable it by making changes to your Android source code:
vendor/friendlyelec/apps# vi device-partial.mk
Remove the comment:
# PRODUCT_PACKAGES += SPI-OLED
Compile Android source code
We connected a FriendlyElec's OLED module which had a 0.96" LCD with a resolution of 128 x 64 and a SPI interface to a NanoPC-T4 and tested it.
The LCD module had 7 pins and here is hardware setup:
6.8.3 APIs for Accessing SPI

Android Utility Function Library
================================
If you need a feature that is native to Linux but not present on other
platforms, construct a platform-dependent implementation that shares
the Linux interface. That way the actual device runs as "light" as
possible.
If that isn't feasible, create a system-independent interface and hide
the details.
The ultimate goal is *not* to create a super-duper platform abstraction
layer. The goal is to provide an optimized solution for Linux with
reasonable implementations for other platforms.
Resource overlay
================
Introduction
------------
Overlay packages are special .apk files which provide no code but
additional resource values (and possibly new configurations) for
resources in other packages. When an application requests resources,
the system will return values from either the application's original
package or any associated overlay package. Any redirection is completely
transparent to the calling application.
Resource values have the following precedence table, listed in
descending precedence.
* overlay package, matching config (eg res/values-en-land)
* original package, matching config
* overlay package, no config (eg res/values)
* original package, no config
During compilation, overlay packages are differentiated from regular
packages by passing the -o flag to aapt.
Background
----------
This section provides generic background material on resources in
Android.
How resources are bundled in .apk files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Android .apk files are .zip files, usually housing .dex code,
certificates and resources, though packages containing resources but
no code are possible. Resources can be divided into the following
categories; a `configuration' indicates a set of phone language, display
density, network operator, etc.
* assets: uncompressed, raw files packaged as part of an .apk and
explicitly referenced by filename. These files are
independent of configuration.
* res/drawable: bitmap or xml graphics. Each file may have different
values depending on configuration.
* res/values: integers, strings, etc. Each resource may have different
values depending on configuration.
Resource meta information and information proper is stored in a binary
format in a named file resources.arsc, bundled as part of the .apk.
Resource IDs and lookup
~~~~~~~~~~~~~~~~~~~~~~~
During compilation, the aapt tool gathers application resources and
generates a resources.arsc file. Each resource name is assigned an
integer ID 0xppttiii (translated to a symbolic name via R.java), where
* pp: corresponds to the package namespace (details below).
* tt: corresponds to the resource type (string, int, etc). Every
resource of the same type within the same package has the same
tt value, but depending on available types, the actual numerical
value may be different between packages.
* iiii: sequential number, assigned in the order resources are found.
Resource values are specified paired with a set of configuration
constraints (the default being the empty set), eg res/values-sv-port
which imposes restrictions on language (Swedish) and display orientation
(portrait). During lookup, every constraint set is matched against the
current configuration, and the value corresponding to the best matching
constraint set is returned (ResourceTypes.{h,cpp}).
Parsing of resources.arsc is handled by ResourceTypes.cpp; this utility
is governed by AssetManager.cpp, which tracks loaded resources per
process.
Assets are looked up by path and filename in AssetManager.cpp. The path
to resources in res/drawable are located by ResourceTypes.cpp and then
handled like assets by AssetManager.cpp. Other resources are handled
solely by ResourceTypes.cpp.
Package ID as namespace
~~~~~~~~~~~~~~~~~~~~~~~
The pp part of a resource ID defines a namespace. Android currently
defines two namespaces:
* 0x01: system resources (pre-installed in framework-res.apk)
* 0x7f: application resources (bundled in the application .apk)
ResourceTypes.cpp supports package IDs between 0x01 and 0x7f
(inclusive); values outside this range are invalid.
Each running (Dalvik) process is assigned a unique instance of
AssetManager, which in turn keeps a forest structure of loaded
resource.arsc files. Normally, this forest is structured as follows,
where mPackageMap is the internal vector employed in ResourceTypes.cpp.
mPackageMap[0x00] -> system package
mPackageMap[0x01] -> NULL
mPackageMap[0x02] -> NULL
...
mPackageMap[0x7f - 2] -> NULL
mPackageMap[0x7f - 1] -> application package
The resource overlay extension
------------------------------
The resource overlay mechanism aims to (partly) shadow and extend
existing resources with new values for defined and new configurations.
Technically, this is achieved by adding resource-only packages (called
overlay packages) to existing resource namespaces, like so:
mPackageMap[0x00] -> system package -> system overlay package
mPackageMap[0x01] -> NULL
mPackageMap[0x02] -> NULL
...
mPackageMap[0x7f - 2] -> NULL
mPackageMap[0x7f - 1] -> application package -> overlay 1 -> overlay 2
The use of overlay resources is completely transparent to
applications; no additional resource identifiers are introduced, only
configuration/value pairs. Any number of overlay packages may be loaded
at a time; overlay packages are agnostic to what they target -- both
system and application resources are fair game.
The package targeted by an overlay package is called the target or
original package.
Resource overlay operates on symbolic resources names. Hence, to
override the string/str1 resources in a package, the overlay package
would include a resource also named string/str1. The end user does not
have to worry about the numeric resources IDs assigned by aapt, as this
is resolved automatically by the system.
As of this writing, the use of resource overlay has not been fully
explored. Until it has, only OEMs are trusted to use resource overlay.
For this reason, overlay packages must reside in /system/overlay.
Resource ID mapping
~~~~~~~~~~~~~~~~~~~
Resource identifiers must be coherent within the same namespace (ie
PackageGroup in ResourceTypes.cpp). Calling applications will refer to
resources using the IDs defined in the original package, but there is no
guarantee aapt has assigned the same ID to the corresponding resource in
an overlay package. To translate between the two, a resource ID mapping
{original ID -> overlay ID} is created during package installation
(PackageManagerService.java) and used during resource lookup. The
mapping is stored in /data/resource-cache, with a @idmap file name
suffix.
The idmap file format is documented in a separate section, below.
Package management
~~~~~~~~~~~~~~~~~~
Packages are managed by the PackageManagerService. Addition and removal
of packages are monitored via the inotify framework, exposed via
android.os.FileObserver.
During initialization of a Dalvik process, ActivityThread.java requests
the process' AssetManager (by proxy, via AssetManager.java and JNI)
to load a list of packages. This list includes overlay packages, if
present.
When a target package or a corresponding overlay package is installed,
the target package's process is stopped and a new idmap is generated.
This is similar to how applications are stopped when their packages are
upgraded.
Creating overlay packages
-------------------------
Overlay packages should contain no code, define (some) resources with
the same type and name as in the original package, and be compiled with
the -o flag passed to aapt.
The aapt -o flag instructs aapt to create an overlay package.
Technically, this means the package will be assigned package id 0x00.
There are no restrictions on overlay packages names, though the naming
convention <original.package.name>.overlay.<name> is recommended.
Example overlay package
~~~~~~~~~~~~~~~~~~~~~~~
To overlay the resource bool/b in package com.foo.bar, to be applied
when the display is in landscape mode, create a new package with
no source code and a single .xml file under res/values-land, with
an entry for bool/b. Compile with aapt -o and place the results in
/system/overlay by adding the following to Android.mk:
LOCAL_AAPT_FLAGS := -o com.foo.bar
LOCAL_MODULE_PATH := $(TARGET_OUT)/overlay
The ID map (idmap) file format
------------------------------
The idmap format is designed for lookup performance. However, leading
and trailing undefined overlay values are discarded to reduce the memory
footprint.
idmap grammar
~~~~~~~~~~~~~
All atoms (names in square brackets) are uint32_t integers. The
idmap-magic constant spells "idmp" in ASCII. Offsets are given relative
to the data_header, not to the beginning of the file.
map := header data
header := idmap-magic <crc32-original-pkg> <crc32-overlay-pkg>
idmap-magic := <0x706d6469>
data := data_header type_block+
data_header := <m> header_block{m}
header_block := <0> | <type_block_offset>
type_block := <n> <id_offset> entry{n}
entry := <resource_id_in_target_package>
idmap example
~~~~~~~~~~~~~
Given a pair of target and overlay packages with CRC sums 0x216a8fe2
and 0x6b9beaec, each defining the following resources
Name Target package Overlay package
string/str0 0x7f010000 -
string/str1 0x7f010001 0x7f010000
string/str2 0x7f010002 -

, can't integrate Dagger2 bacause of error “Activity cannot be provided without an @Inject constructor ”
I want to integrate Dagger2, but i cant' build my project, build failed with:
error: com.example.animalslibrary.ui.home.activity.HomeActivity cannot be provided without an @Inject constructor or from an @Provides-annotated method. com.example.animalslibrary.ui.home.activity.HomeActivity is injected at com.example.animalslibrary.AppComponent.injectsHomeActivity(homeActivity)
I looking for answer about 3 hours, and i asking you for help now.
My actions step by step:
1) Add depenceses to Gradle:
implementation 'com.google.dagger:dagger:2.7' annotationProcessor 'com.google.dagger:dagger-compiler:2.7'
2) Create empty test class
NetworkUtils:
public class NetworksUtils { }
3) Create module for it:
@Module public class NetworksModule { @Provides NetworksUtils provideNetworksUtils() { return new NetworksUtils(); } }
4) Create "connection" interface:
import dagger.Component; @Component(modules = NetworksModule.class) public interface AppComponent { void injectsHomeActivity(HomeActivity homeActivity); }
5) Create
App class. I don't completle understand why i did this(teaching by guide),exactly i don't understand why i need to extend by
Application. Maybe to create all components when application starts.
DaggerAppComponent is red, because of failed while building, this class does't created yet.
public class App extends Application { private static AppComponent component; @Override public void onCreate() { super.onCreate(); component = DaggerAppComponent.create(); } public static AppComponent getComponent() { return component; } }
6) Add
App to manifest:
<application android:name="com.example.animalslibrary.ui.App" ...
7) Now i write my
HomeActivity class...
public class HomeActivity extends AppCompatActivity implements HomeContract.View { ... @Inject private NetwotkUtils netwotkUtils; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_home); ... App.getComponent().injectsHomeActivity(this); ... }
8)...and goes down when try to build project.
I think my error about
App, but i can't understand where and how fix it.
UPD:
This modification is not helped:

Detect a face with OpenCV
Please Note: This Post refers to OpenCV 2.x!
The following sample uses the classes
videoand
common, which are helper classes from the
samples/python2 folder.
The cascades used in this sample are located in the
data folder of your OpenCV download, so you'll probably need to adjust the filename parameter
cascade_fn to make this example work:
import cv2 from video import create_capture from common import clock, draw_str # You probably need to adjust some of these: video_src = 0 cascade_fn = "haarcascades/haarcascade_frontalface_default.xml" # Create a new CascadeClassifier from given cascade file: cascade = cv2.CascadeClassifier(cascade_fn) cam = create_capture(video_src) while True: ret, img = cam.read() # Do a little preprocessing: img_copy = cv2.resize(img, (img.shape[1]/2, img.shape[0]/2)) gray = cv2.cvtColor(img_copy, cv2.COLOR_BGR2GRAY) gray = cv2.equalizeHist(gray) # Detect the faces (probably research for the options!): rects = cascade.detectMultiScale(gray) # Make a copy as we don't want to draw on the original image: for x, y, width, height in rects: cv2.rectangle(img_copy, (x, y), (x+width, y+height), (255,0,0), 2) cv2.imshow('facedetect', img_copy) if cv2.waitKey(20) == 27: break | https://www.bytefish.de/blog/object_detection.html | CC-MAIN-2020-40 | en | refinedweb |
What are generators?
Generators are helper programs that output test. Most programming task usually has a large input (for example, an array of up to 2 * 105 elements, a tree of up to 105 vertices), so it's not possible to add all the tests manually. In these cases, generators come to the rescue.
If you are writing a generator in C++, it is recommended to use the testlib.h library.
Types of generators
There are two types of generators:
- Single-test generator: output exactly one test in a single run. Usually, to generate several tests, one must run the generator several times with different command line parameters. Such generators output the test to the standard output stream (to the screen).
- Multiple-test generator: output many tests in a single run. Such generators output tests to files (one file for each test).
An example single-test generator with testlib.h
The following generator output a pair of integers with each element from 1 to n — where n is a command line parameter passed to the generator.
#include "testlib.h" #include <iostream> using namespace std; int main(int argc, char* argv[]) { registerGen(argc, argv, 1); int n = atoi(argv[1]); cout << rnd.next(1, n) << " "; cout << rnd.next(1, n) << endl; }
Why testlib.h?
On the surface, it seems that testlib.h is not necessary to write a generator. This is not true. Almost all generators need to generate random values, and it is tempted to use
rand(). However, this is a bad practice. A basic principle of writing generators is that: a generator must output the same test when compiled by any compiler on any platform if it is run in the same way (using the same command line parameters). When using
rand() or C++11 classes like
mt19937/uniform_int_distribution, your program will output different tests when compiled with different compilers.
The random value generator in testlib.h ensures that the same value is generated regardless of the (test) generator and platform. Besides, testlib.h has various conveniences for generating tests, for example,
rnd.next("[a-z]{1,10}") will return a random word of length 1 to 10 from letters a to z.
Translator's note: There are more issues with using
rand() aside from the above one. Refer to this blog for a detailed explanation about these issues.
Available method
To initialize a testlib generator, the first line of your generator must be of the form
registerGen(argc, argv, 1); (where 1 is the version of the random number generator used). After that, it will be possible to use the
rnd object, which will be initialized with a hash from all the command line arguments. Thus, the output of
g 100 and
g.exe "100" will be the same, while
g 100 0 will be different.
rnd is of type
random_t. That is, you can create your own generator, but this is not necessary in most of the cases.
rnd has many useful member functions. Here are some examples:
Also, please do not use
std::random_shuffle, use the
shuffle from testlib.h instead. It also takes two iterators, but works using
rnd.
Translator's note: If my understanding is correct,
rnd.wnext is defined as follows:
Example: generating an undirected tree
Below is the code of an undirected tree generator that takes two parameters — the number of vertices and the 'elongation' of the tree. For example:
- For n = 10, t = 1000, a path graph (degree of all vertices are at most 2) is likely to be generated
- For n = 10, t = - 1000, a star graph (there's only one non-leaf vertex in the tree) is likely to be generated.
registerGen(argc, argv, 1); int n = atoi(argv[1]); int t = atoi(argv[2]); vector<int> p(n); /* setup parents for vertices 1..n-1 */ for(int i = 0; i < n; ++i) if (i > 0) p[i] = rnd.wnext(i, t); printf("%d\n", n); /* shuffle vertices 1..n-1 */ vector<int> perm(n); for(int i = 0; i < n; ++i) perm[i] = i; shuffle(perm.begin() + 1, perm.end()); /* put edges considering shuffled vertices */ vector<pair<int,int> > edges; for (int i = 1; i < n; i++) if (rnd.next(2)) edges.push_back(make_pair(perm[i], perm[p[i]])); else edges.push_back(make_pair(perm[p[i]], perm[i])); /* shuffle edges */ shuffle(edges.begin(), edges.end()); for (int i = 0; i + 1 < n; i++) printf("%d %d\n", edges[i].first + 1, edges[i].second + 1);
How to write a multiple-test generator?
A multiple-test generator in one execution can output more than one test. Tests by such a generator are output to files. In the generator on testlib.h it is enough to write
startTest(test_index) before the test output. This will re-open (
freopen) the standard output stream to a file named
test_index.
Please note that if you are working with the Polygon system, in this case, you need to write something like
multigen a b c > {4-10} in the script (if it is assumed that starting the multiple-test generator will return tests 4, 5, 6, 7, 8, 9, and 10).
Other notes about generators
- Strictly follow the format of the test — spaces and line breaks should be placed correctly. The test should end with a line feed. For example, if the test consists of a single number, then output it as
cout << rnd.next (1, n) << endl;— with a line feed at the end.
- If the test size is large, it is prefered to use
printfinstead of
cout— this will improve the performance of the generator.
- It is better to use
coutto output
long long, but if you want
printf, then use the
I64constant (for example,
printf(I64, x);).
- Please be aware about various cases of C++ undefined behavior. For example, in the first example generator above, if the two
coutcommands are combined into one, the order of the
rnd.nextfunction calls is not defined.
Translator's note: about the third point, using
lld constant with
printf to output
long long used to be problematic in the past, but is no longer an issue now.

Snippets
With GitLab Snippets you can store and share bits of code and text with other users.
Snippets can be maintained using snippets API.
There are two types of snippets:
- Personal snippets.
- Project snippets.
Personal snippets
Personal snippets are not related to any project and can be created completely independently. There are 3 visibility levels that can be set, public, internal and private. See Public access for more information.
Project snippets
Project snippets are always related to a specific project. See Project features for more information.
Create a snippet
To create a personal snippet, click the plus icon () on the top navigation and select New snippet from the dropdown menu:
If you’re on a project’s page but you want to create a new personal snippet, click the plus icon () and select New snippet from the lower part of the dropdown (GitLab on GitLab.com; Your Instance on self-managed instances):
To create a project snippet, navigate to your project’s page and click the plus icon (), then select New snippet from the upper part of the dropdown (This project).
From there, add the Title, Description, and a File name with the
appropriate extension (for example,
example.rb,
index.html).
Versioned Snippets
Introduced in GitLab 13.0.
Starting in 13.0, snippets (both personal and project snippets) have version control enabled by default.
This means that all snippets get their own underlying repository initialized with
a
master branch at the moment the snippet is created. Whenever a change to the snippet is saved, a
new commit to the master branch is recorded. Commit messages are automatically
generated. The snippet’s repository has only one branch (master) by default, deleting
it or creating other branches is not supported.
Existing snippets will be automatically migrated in 13.0. Their current content will be saved as the initial commit to the snippets’ repository.
File names
Snippets support syntax highlighting based on the filename and extension provided for them. While it is possible to submit a snippet without specifying a filename and extension, it needs a valid name so the content can be created as a file in the snippet’s repository.
In case the user does not attribute a filename and extension to a snippet,
GitLab automatically adds a filename in the format
snippetfile<x>.txt
where
<x> represents a number added to the file, starting with 1. This
number increases incrementally when more snippets without an attributed
filename are added.
When upgrading from an earlier version of GitLab to 13.0, existing snippets
without a supported filename will be renamed to a compatible format. For
example, if the snippet’s filename is it will
be changed to
http-a-weird-filename-me to be included in the snippet’s
repository. As snippets are stored by ID, changing their filenames will not break
direct or embedded links to the snippet.
Cloning snippets
Snippets can be cloned as a regular Git repository using SSH or HTTPS. Click the Clone button above the snippet content to copy the URL of your choice.
This allows you to have a local copy of the snippet’s repository and make changes as needed. You can commit those changes and push them to the remote master branch.
Reduce snippets repository size
Since versioned Snippets are considered as part of the namespace storage size, it’s recommended to keep snippets’ repositories as compact as possible.
For more information about tools to compact repositories, see the documentation on reducing repository size.
Limitations
- Binary files are not supported.
- Creating or deleting branches is not supported. Only a default master. branch is used.
- Git tags are not supported in snippet repositories.
- Snippets’ repositories are limited to one file. Attempting to push more than one file will result in an error.
- Revisions are not yet visible to the user on the GitLab UI, but it’s planned to be added in future iterations. See the revisions tab issue for updates.
- The maximum size for a snippet is 50 MB, by default.
Discover. comments
Introduced in GitLab 9.2.
With GitLab Snippets you engage in a conversation about that piece of code, facilitating the collaboration among users.
Downloading snippets
Introduced in GitLab 10.8.
Public snippets can not only be shared, but also embedded on any website. With this, you” button. This copies a one-line script that you can add to any website or blog post.
Here’s how an example code looks like:
<script src=""></script>
Here’s how an embedded snippet looks like:
Embedded snippets are displayed with a header that shows the file name if it’s defined, the snippet size, a link to GitLab, and the actual snippet content. Actions in the header allow users to see the snippet in raw format and download it. | https://docs.gitlab.com/ee/user/snippets.html | CC-MAIN-2020-40 | en | refinedweb |

External view of a routing entry.
OLSRv1, unlike OSPF, does not implement areas, therefore there is no need in the current design to have logical separation between the routes which it processes internally and those which it exports to the RIB.
It also has no concept of network LSAs [HNA routes are not used in calculating reachability in the OLSR topology] therefore the address property is not present here, nor is the 'discard' flag, nor is the path type.
TODO: Import this definition into UML. TODO: Templatize to hold IPv6.
This is the base class from which RIB routing table entries are derived. It's not useful by itself.
This class is used for storing RIPv2 and RIPng route entries. It is a template class taking an address family type as a template argument. Only IPv4 and IPv6 types may be supplied.
Constructor for a route entry.
Destructor.
Cleans up state associated with RouteEntry. If the Origin associated with the RouteEntry is not-null, the Origin is informed of the destruction.
Get the Administrative Distance.
Reimplemented in IPRouteEntry< A >.
Set OLSR protocol cost of route.
Set if this route has been filtered by policy filters.
Set if route is accepted or rejected.
Set protocol address of next hop.

Functional field output before save and Editable field?.
In openerp 7 Is it possible to functional field output shows before save the records and Editable functional field?
I think yes.
Example on_change method:. link text
Just add any field for output in your result.
def custom_function(self, cr, uid, ids, field_name_from_xml, context=None): # work with input data #... your result in custom_addr custom_addr = 'Barcelona' return { 'value': { 'address': custom_addr # adress is must in your xml declaration in this case } }

Configuring a Table Cell Span Provider
In a custom framework, the
table element can have cells that span over multiple columns and rows. As
explained in Configuring Tables, you need to indicate Oxygen XML Author a method to determine the cell spanning. If
you use the cell element attributes
rowspan and
colspan or
rows and
cols, Oxygen XML Author can determine the
cell spanning automatically. In our example the
td element uses the
attributes
row_span and
column_span that are not
recognized by default. You will need to implement a Java extension class for defining the
cell spanning.
- Create the class simple.documentation.framework.TableCellSpanProvider. This class must implement the ro.sync.ecss.extensions.api.AuthorTableCellSpanProvider interface.
import ro.sync.ecss.extensions.api.AuthorTableCellSpanProvider; import ro.sync.ecss.extensions.api.node.AttrValue; import ro.sync.ecss.extensions.api.node.AuthorElement; public class TableCellSpanProvider implements AuthorTableCellSpanProvider {
- The init method is taking as argument the ro.sync.ecss.extensions.api.node.AuthorElement that represents the XML
tableelement. In our case the cell span is specified for each of the cells so you leave this method empty. However, there are cases (such as the CALS table model) when the cell spanning is specified in the
tableelement. In such cases, you must collect the span information by analyzing the
tableelement.
public void init(AuthorElement table) { }
- The getColSpan method is taking as argument the table cell. The table layout engine will ask this AuthorTableSpanSupport implementation what is the column span and the row span for each XML element from the table that was marked as cell in the CSS using the property
display:table-cell. The implementation is simple and just parses the value of column_span attribute. The method must return
nullfor all the cells that do not change the span specification.
public Integer getColSpan(AuthorElement cell) { Integer colSpan = null; AttrValue attrValue = cell.getAttribute("column_span"); if(attrValue != null) { // The attribute was found. String cs = attrValue.getValue(); if(cs != null) { try { colSpan = new Integer(cs); } catch (NumberFormatException ex) { // The attribute value was not a number. } } } return colSpan; }
- The row span is determined in a similar manner:
public Integer getRowSpan(AuthorElement cell) { Integer rowSpan = null; AttrValue attrValue = cell.getAttribute("row_span"); if(attrValue != null) { // The attribute was found. String rs = attrValue.getValue(); if(rs != null) { try { rowSpan = new Integer(rs); } catch (NumberFormatException ex) { // The attribute value was not a number. } } } return rowSpan; }
- The method hasColumnSpecifications always returns
trueconsidering column specifications always available.
public boolean hasColumnSpecifications(AuthorElement tableElement) { return true; }Note: The complete source code for framework customization examples can be found in the oxygen-sample-framework module of the Oxygen SDK , available as a Maven archetype on the Oxygen XML Author website.
- In the listing below, the XML document contains the table element:
<table> <header> <td>C1</td> <td>C2</td> <td>C3</td> <td>C4</td> </header> <tr> <td>cs=1, rs=1</td> <td column_span="2" row_span="2">cs=2, rs=2</td> <td row_span="3">cs=1, rs=3</td> </tr> <tr> <td>cs=1, rs=1</td> </tr> <tr> <td column_span="3">cs=3, rs=1</td> </tr> </table>
When no table cell span provider is specified, the table has the following layout:
Figure: Table layout when no cell span provider is specified
When the above implementation is configured, the table has the correct layout:
Figure: Cells spanning multiple rows and columns.

.
When using Selenium Webdriver, the control of browser and the application is with the reference variable of type WebDriver, i.e. the WebDriver reference variable can identify any web element present on the page. But it doesn’t have the ability to handle all the keyboard & mouse events like right-click, drag & drop, etc. Therefore WebDriver reference variable alone is NOT sufficient to automate every user action. But don’t worry! As stated earlier, Selenium Webdriver provides an Advanced User Interaction API (including Actions class) which facilitate keyboard and mouse actions.
import org.openqa.selenium.interactions.Actions;
Actions class in Selenium Webdriver
The Actions class is a user-facing API for emulating complex keyboard and mouse actions in Selenium Webdriver. You can directly use this class rather than using the input devices, i.e. Keyboard or Mouse. It Implements builder pattern, in which a complex object is constructed, i.e. builds a “Composite Action” containing all actions specified by the individual method calls. For e.g. Composite Action: Mouse Hover >> Click.
public class Actions
extends java.lang.Object
Default constructor below uses the default keyboard, mouse implemented by the driver.
Actions(WebDriver driver)
- Import the package to access the actions class methods.
- Create the actions class object
- Access the range of available methods.
// Create the Actions class object
Actions builder = new Actions(driver);
// To focus (mouse hover) on element
builder.moveToElement(element).perform();
Note: Perform method is used here to execute the action.
Execute multiple actions using build()
Above we simply performed one action on the element (mouse hover), in case we want to perform sequence of events on the same element, it can be done using build method.
// To focus and then click on the element
builder.moveToElement(element).click().build().perform();
Keyboard and Mouse Actions in Selenium Webdriver
Mouse Actions in Selenium Webdriver
Below actions help in simulating mouse events in case of automation using Selenium Webdriver.
- public Actions click() — Clicks at the current mouse location. Useful when combined with
- public Actions click(WebElement onElement) — Clicks in the middle of the given element (onElement).
- public Actions clickAndHold() — Clicks (without releasing) at the current mouse location.
- public Actions clickAndHold(WebElement onElement) — Clicks (without releasing) in the middle of the given element (onElement)
- public Actions contextClick() — Performs a context-click at the current mouse location.
- public Actions contextClick(WebElement onElement) — Performs a context-click at middle of the given element (onElement)
- public Actions doubleClick() — Performs a double-click at the current mouse location.
- public Actions doubleClick(WebElement onElement) — Performs a double-click at middle of the given element (onElement)
- public Actions dragAndDrop(WebElement source, WebElement target) — A convenience method that performs click-and-hold at the location of the source element, moves to the location of the target element, then releases the mouse.
- public Actions dragAndDropBy(WebElement source, int xOffset, int yOffset) — a convenience method that performs click-and-hold at the location of the source element, moves by a given offset, then releases the mouse.
- public Actions moveByOffset(int xOffset, int yOffset) — Moves the mouse from its current position (or 0,0) by the given offset. If the coordinates provided are outside the viewport (the mouse will end up outside the browser window) then the viewport is scrolled to match.
- public Actions moveToElement(WebElement toElement) — Moves the mouse to the middle of the element. The element is scrolled into view and its location is calculated using getBoundingClientRect.
- public Actions moveToElement(WebElement toElement, int xOffset, int yOffset) — Moves the mouse to an offset from the top-left corner of the element. The element is scrolled into view and its location is calculated using getBoundingClientRect.
- public Actions release() — Releases the depressed left mouse button at the current mouse location.
- public Actions release(WebElement onElement) — Releases the depressed left mouse button, in the middle of the given element. Invoking this action without invoking clickAndHold()first will result in undefined behaviour.
Keyboard Actions in Selenium Webdriver
keyDown and keyUp are the two main methods available under Selenium Webdriver Actions class.
- public Actions keyDown(Keys theKey) — Performs a modifier key press (SHIFT,Keys.ALT or Keys.CONTROL). Does not release the key – subsequent interactions may assume it’s kept pressed. Note that the key is never released implicitly – eitherkeyUp(theKey) or sendKeys(Keys.NULL) must be called to release.
- public Actions keyDown(WebElement element, Keys theKey) — Performs a modifier key press (SHIFT,Keys.ALT or Keys.CONTROL) after focusing on an element.
- public Actions keyUp(Keys theKey) — Performs a modifier key release (SHIFT,Keys.ALT or Keys.CONTROL). Releasing a non-depressed modifier key will yield undefined behaviour.
- public Actions keyUp(WebElement element, Keys theKey) — performs a modifier key release after focusing on an element.
- public Actions sendKeys(java.lang.CharSequence… keysToSend) — Sends keys to the active element. This differs from calling sendKeys(CharSequence…) on the active element in two ways: The modifier keys included in this call are not released and there is no attempt to re-focus the element. So sendKeys(Keys.TAB) for switching elements should work.
- public Actions sendKeys(WebElement element, java.lang.CharSequence… keysToSend) — Sends keys to the given element.
Generic Actions
- public Action build() — Generates a composite action containing all actions so far, ready to be performed. It resets the internal builder state, so subsequent calls to build() will contain fresh sequences.
- public Actions pause(long pause) — Performs a pause. It’s deprecated since‘Pause’ is considered to be a bad design practice.
- public void perform() — A convenience method for performing the actions without calling build() first.
I know all these methods together will be too much to grab as of now. But don’t worry! In subsequent articles we will learn about the commonly used keyboard and mouse actions in Selenium Webdriver.

hi, i was implementing strstr() to see how it works.
Code:#include<iostream> using namespace std; int main() { char str[] = "this is a test"; char*s; s=strstr(str,"test"); cout<<s<<endl; }
i have two question .
question 1 > what is the full form of strstr() ?
for example, if i write strcpy ---> it means string copy.
similarly what is the meaning of strstr() ?
the syntaxex dont give the full form of this function. can you tell what is the literal meaning?
question 2.
without assigning a memory (by new keyword ) the code is running!!
look, i have simply tested with only char *s; but no memory allocated. | https://cboard.cprogramming.com/c-programming/51771-strstr-question.html | CC-MAIN-2018-05 | en | refinedweb |

I think in most of the examples that I didn't know how to rewrite, this was basically the issue. On the other hand, I do think that lambdas get overused, as indicated by the number of examples I *was* able to rewrite.[1] Still, I have to admit that in some cases (especially those involving reduce), I wish the coder had named the function -- it would have given me a little bit more documentation as to what the code was trying to do. On the other hand, in other cases, like when a function is a keyword argument to another function (e.g. inspect.py's "def formatargspec..." example) using a def statement and naming the function would be redundant. Steve [1] Note that this isn't entirely fair to the examples, some of which were written before list comprehensions, generator expressions and itemgetter/attrgetter. | https://mail.python.org/pipermail/python-list/2004-December/264458.html | CC-MAIN-2018-05 | en | refinedweb |
C and C++, the language supports a simple macro preprocessor. Source lines that should be handled by the preprocessor, such as
#define and
#include are referred to as preprocessor directives.
Another C construct, the
#pragma directive, is used to instruct the compiler to use pragmatic or implementation-dependent features. Two notable users of this directive are OpenMP and OpenACC.
Syntactic constructs similar to C's preprocessor directives, such as C#'s
#if, are also typically called "directives", although in these cases there may not be any real preprocessing phase involved.
All preprocessor commands begin with a hash symbol (#).
Directives date to ALGOL 68, where they are known as pragmats (from "pragmatic"), and denoted pragmat or pr; in newer languages, notably C, this has been abbreviated to "pragma" (no 't').
A common use of pragmats in ALGOL 68 is in specifying a stropping regime, meaning "how keywords are indicated". Various such directives follow, specifying the POINT, UPPER, RES (reserved), or quote regimes. Note the use of stropping for the pragmat keyword itself (abbreviated pr), either in the POINT or quote regimes:
.PR POINT .PR .PR UPPER .PR .PR RES .PR 'pr' quote 'pr'
Today directives are best known in the C language, of early 1970s vintage, and continued through the current C99 standard, where they are either instructions to the C preprocessor, or, in the form of
#pragma, directives to the compiler itself. They are also used to some degree in more modern languages; see below.
declareconstruct (also
proclaimor
declaim).[1] With one exception, declarations are optional, and do not affect the semantics of the program. The one exception is
special, which must be specified where appropriate.
#include "file"directive is the significant comment
{$I "file"}.
use", which imports modules, can also be used to specify directives, such as
use strict;or
use utf8;.

from __future__ import feature(defined in PEP 236 -- Back to the __future__), which changes language features (and uses the existing module import syntax, as in Perl), and the
codingdirective (in a comment) to specify the encoding of a source code file (defined in PEP 263 -- Defining Python Source Code Encodings). A more general directive statement was proposed and rejected in PEP 244 -- The `directive' statement; these all date to 2001.
usesyntax for directives, with the difference that pragmas are declared as string literals (e.g.
"use strict";, or
"use asm";), rather than a function call.
Option" is used for directives:
Option Explicit On|Off- When on disallows implicit declaration of variables at first use requiring explicit declaration beforehand.
Option Compare Binary- Results in string comparisons based on a sort order derived from the internal binary representations of the characters - e.g. for the English/European code page (ANSI 1252) A < B < E < Z < a < b < e < z < À < Ê < Ø < à < ê < ø. Affects intrinsic operators (e.g. =, <>, <, >), the Select Case block, and VB runtime library string functions (e.g. InStr).
Option Compare Text- Results in string comparisons based on a case-insensitive text sort order determined by your system's locale - e.g. for the English/European code page (ANSI 1252) (A=a) < (À = à) < (B=b) < (E=e) < (Ê = ê) < (Z=z) < (Ø = ø). Affects intrinsic operators (e.g. =, <>, <, >), the Select Case block, and VB runtime library string functions (e.g. InStr).
Option Strict On|Off- When on disallows:
Option Infer On|Off- When on enables the compiler to infer the type of local variables from their initializers.

Follow these steps to implement:
- Choose any element of the list to be the pivot.
- Divide all other elements (except the pivot) into two partitions.
- All elements less than the pivot must be in the first partition (lower half list).
- All elements greater than the pivot must be in the second partition (upper half list).
- Use recursion to sort both partitions.
- Join the first sorted partition, the pivot, and the second sorted partition
def qsort(list): if not list: return [] else: pivot = list[0] less = [x for x in list if x < pivot] more = [x for x in list[1:] if x >= pivot] return qsort(less) + [pivot] + qsort(more)
Example:
someList = [3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5, 8, 9, 7, 9, 3]
print qsort( someList )
[1, 1, 2, 3, 3, 3, 4, 5, 5, 5, 6, 7, 8, 9, 9, 9]
Enjoy the sort. | https://anothergisblog.blogspot.com/2012/05/quicksort-using-python.html | CC-MAIN-2018-05 | en | refinedweb |
Example:
import arcpy
ds = r"c:\temp\sample.gdb\Parcels"
g = arcpy.Geometry()
geomList = arcpy.CopyFeatures_management(ds,g)
# Get the Area (Sq Ft)
area = 0.0
for geom in geomList:
area += geom.area
print "Total Parcel Area: {0}".format(area)
The CopyFeatures() copies the results as a geometry object to a list and the area property is a standard Geometry object property.

Hi,
I want to use mate-dock-applet, which is available i the repositories, but when I try to use it, it never runs and instead it complains with:
[...]
ImportError: requiring namespace 'Gtk' version '3.0', but '2.0' is already loaded
[...]
I understand the issue, but I was under the impression that MATE is Gtk3 now?
This is on 18.2 and 18.3 BTW.
Any help would be great!

Overview
In this tutorial we will demonstrate how to integrate Realm’s Event Framework, available in the Professional and Enterprise editions, with a machine learning service from IBM’s Watson Bluemix service. This service will perform text and facial recognition processing on an image you provide and return to you descriptions of any faces found in the image as well any text that the machine learning algorithms find in that image.
The app we’re going to build is called Scanner. It is a very simple single-view application that allows users to take a picture (or select an image from the photo library) and get back detailed information about that picture identified by Watson. The application is implemented in 2 parts:
A mobile client that allows the user to take pictures with the phone’s camera; these images are synchronized with the remote Realm Object Server.
An event handler on a Realm Object Server that watches for new images taken by mobile clients, and then sends them to be analyzed by IBM’s Watson via the Bluemix service.
Scanner is implemented as a native app for both iOS and Android. The Github repo for the source code is provided at the end of this tutorial, but we encourage you to follow along as we construct the app in Swift (iOS) or Java (Android) code respectively.
The server side is implemented as a single JavaScript file which will be explained as we go along as well.
Prerequisites
In order to get up and running with this tutorial, you will need to have a few development tools setup, and you will need to sign up for a free API key for the IBM Bluemix service that does the image processing. All the prerequisites and setup steps are listed below:
For iOS, you will need Xcode 8.1 and an active Apple developer account (in order to sign the application and run on real hardware); for Android you will need Android Studio version 2.2 or higher.
For the Realm Object Server, you will need a Macintosh running macOS 10.11 or higher, or Linux server running CentOS 6 or 7, or Ubuntu 16.04. Follow the installation instructions for the Professional or Enterprise Editions provided via email. You can sign up for a free 14-day trial of the Professional Edition here.
Make note of the admin user account & password you created when the Realm Object Server was registered - we will use this as the user for our demo application in this tutorial.
For access to IBM’s Watson visual recognition system it will be necessary to create a Bluemix trial account using the following URL:. The steps require an active/verifiable email address and will result in the generation of an API key for the Watson components of the Bluemix services. The steps are summarized as follows:
Follow URL above to create an IBM Bluemix account
Receive verification email; click on link to verify
Log in to IBM Bluemix portal
Select a region - there are 3 choices: Sydney, United Kingdom and US South - pick the region that is closest to you.
Name your workspace - this name can be anything you like.
Click on the “I’m Ready” button to create the workspace
Once on the Apps page, click on the “hamburger menu” (upper left corner of the browser); click “services” to reveal the available services, then “Watson” to get to the Watson page
On the Watson page, click “Create Watson Service”
One the Watson Services page, click on the “Visual Recognition” item
At the top of the following page click on the “free” plan, then “create”
Lastly click “view credentials” and copy the JSON block that includes the api_key. This will be needed later in this tutorial to setup access for your application.
Starting the Object Server & Finding the AdminToken
Before we dive into this tutorial, it’s a good idea to have the Realm Object Server started and identify the Admin Token that will be needed in the implementation sections to follow.
If you downloaded the macOS version of the Realm Mobile Platform, follow the instructions in the download kit to start the server.
Once the server is running you will need a copy of the “admin token” which is displayed in the terminal window as part of the startup process. The admin token looks very much like this:
Your admin access token is: ewoJImlkZW50aXR5IjogImFkbWluIiwKCSJhY2Nlc3MiOiBbInVwb G9hZCIsICJkb3dubG9hZCIsICJtYW5hZ2UiXQp9Cg==:A+UUfCEap6ikwX5nLB0mBcjHx1RVqBQjmYJ3j BNP00xum65DT0tZV/oq2W8VIeuPiASXt3Ndn5TkahTU6a5UxQCnODfu0aGclgBuHmv5CKXwm4qr4bwL+ yd80WlRojdmYrYUf5jjbQjuBLUXkhyX554TjHOmANYzw1fv6sp1YXKDuKDkCHpH8+GIG5u0Xjp6IUK6F tPtMbiPS1mMZ3YnxHm5BB2RQH3ywGxlsYLFnA9l4+Dc++sEQGWviYCCNBL9fD49zFPdvfBoc1WqsFi3P KKcqyXfGdnyYucrDfo/4Rn8mT95lAqJGCcIRWwiNYKI805uHcI+JFv6/YXJB0wEMw==
The token itself is all the text after the
Your admin access token is: text, up to and including the trailing
== characters.
If you’ve installed any of the Linux versions the software, the server will be automatically started for you and the admin token can be found in the file
/etc/realm/admin_token.base64.
You will need this token for server sections of this tutorial.
Architecture
The architecture of this client and server is quite simple:
There are 3 main components:
The Realm Mobile Clients
The clients is a small application that allows the user to take a picture and a Realm Database to store images and communicate with the Realm Object Server
The Realm Object Server
This is the part of the system that synchronizes data between mobile clients.
The Realm Event Framework
This is the part of the Realm Object Server that can be programmed to respond to changes in a Realm database and perform actions based on those changes. In this case the action will be to interact with the IBM Bluemix recognition API using pictures captured by mobile clients and return any resulting text and descriptions of people (if any) in the image to the client Realms.
Operation
The operation of the system is equally simple:
Client devices take pictures that are stored in a Realm Database and synchronized with the Realm Object Server. An event listener on the Realm Object Server observes client Realms and notices when new pictures have been taken by client devices. The listener sends these images to be processed by the IBM Watson recognition service. When results come back, any scanned text is updated in the specific client’s Realm and these results are synchronized back to the respective mobile client where they can be viewed by the user.
Models & Realms
The cornerstone of information sharing in the Realm Mobile Platform is a shared model (or schema) between the clients and the server. Realm models are simple to define, yet cover all of the basic data types found in all programming languages (e.g., booleans, integers - Int8, Int16, Int32, Int64, – Doubles, Floats, and Strings) as well as a few higher-order types such as collection types like Lists, dates, a raw binary data type, etc.
More info on supported types and model definitions can be found in the Realm Mobile Database documentation; the version linked to here is for Apple’s Swift, but matching documents cover Java and other language bindings Realm supports.
There’s one model needed to support this text scanning app:
The “Scan” model which has a couple of string fields to hold the status returned by the Watson Bluemix image recognition service and a “scan id” to uniquely identify a new events (pictures taken), and a raw binary data type field to hold the bytes of the picture that is synchronized between the mobile device and the Realm Object Server.
Once a client starts up, this model is synchronized and exists both in the client and the server. The model is accessed as an named entity called a Realm. This example uses a Realm containing a single model but Realms can hold multiple models and, conversely a single app can access many Realms. For this example we’ll call the Realm
scanner.
Realm Paths
On the client side – where a pictures is selected – there is a local on-device Realm called
scanner. And, on the Realm Object Server there is one Realm per mobile device also called
scanner - these contain the data that is synchronized from the mobile device to the server and back again as the objects, either added, deleted, or updated.
On the Object Server the
scanner Realm exist in a hierarchy of Realms that are arranged much like a filesystem with a root (“/”), a user ID that is unique to each mobile user represented by a long string of numbers, a path separator (another “/” character) and then the name of the Realm that contains the models and their data. This is union of path + a user ID + realm-name is called the Realm Path and looks very much like a file system path or even like a URL.
To see how this looks in action - Let’s consider 2 hypothetical users of our Scanner app, their Realms on the object server might be written like this:
/12345467890/scanner /9876543210/scanner
The Realm Object Server allows us to access Realms as URLs, so we actually refer to a synchronized Realm from inside a mobile app as follows:
realm://127.0.0.1:9080/~/scanner
Where the “realm://127.0.0.1:9080” represents the access scheme (“realm://”), the server IP address (or DNS hostname) and port number of the Realm Object server. The “~” (tilde) character is shorthand for “my user ID” and “scannner” is, as previously mentioned, the name of the Realm that contains our
Scan model.
This concept of a Realm URL will become clearer as we implement the client and server sides of Scanner.
The Realm Event Framework
The final concept, and the driving force behind this demo, is the Realm Event Framework. This is the mechanism that allows the Object Server to respond to changes in the Realms it manages. Unlike Realm specific listeners, this API allows developers to listen for changes across Realms.
Global Event Listeners are written in JavaScript and run in the context of a Node.js application and are written as a function to which 2 primary parameters are passed:
Change Event Callback - this specifies what is to be done once a change has been detected. In our case this will be calling the IBM Bluemix recognition API and processing any results that come back from the remote server.
Regex Pattern - this specifies which Realms on the server the listener applies to. In our case we will be listening to Realms that match “.*/scanner” or all the Realms created by each user of the Scanner app.
Here is an example of a change event callback:
var change_event_callback = function(change_object) { // Called on when changes are made to any Realm which match the given regular expression // // The change_object has the following parameters: // path: The path of the changed Realm // realm: The changed realm // oldRealm: The changed Realm at the old state before the changes were applied // changes: The change indexes for all added, removed, and modified objects in the changed Realm. // This object is a hashmap of object types to arrays of indexes for all changed objects: // { // object_type_1: { // insertions: [indexes...], // deletions: [indexes...], // modifications: [indexes...] // }, // object_type_2: // ... // }
To register a Global Event Listener you call this API:
Realm.Sync.addListener(server_url, admin_user, regex, change_callback) {};
Notice that the remaining parameters provided include the URL of the Realm Object Server that contains the Realms and an admin user credential that uses the Admin Token we saw back when we started the Realm Object Server.
Don’t be concerned if this syntax isn’t familiar, these are examples within the larger framework of how a Realm Event is processed and will be shown in context as we implement the server side of the Scanner application.
With these concepts we have all we need to implement our Scanner.
Implementation
Building the Server Application
We will start with the Realm Object Server implementation first since it is needed regardless of which client application – iOS or Android – you choose to use. In order to continue we expect that following are true:
You have downloaded and installed a version of the Realm Mobile Platform Professional or Enterprise Edition.
You have successfully started the server and can access (copy) the Admin Token for your running server
You can log in to your Linux server or access the Mac on which the Realm Object Server is running.
You have obtained an API Key for the IBM Bluemix Watson service.
Creating the server side scripts.
Create a directory - You will need to create a new directory on your server (or in a convenient place on your Mac if running the Mac version) in which to place the server files. We are using the name
ScannerServer which will include the Node.js package dependency file. Change into this directory and create/edit a file called
package.json - this is a Node.js convention that is used to specify external package dependencies for a Node application as well as specifics about the application itself (its name, version number, etc). The contents should be:
{ "name": "Scanner", "version": "0.0.1", "description": "Use Realm Object Server's event-handling capabilities to react to uploaded images and send them to Watson for image recognition.", "main": "index.js", "author": "Realm", "dependencies": { "realm": "file:realm-1.0.0-BETA-3.0-professional.tgz", "watson-developer-cloud": "^2.11.0" } }
Notice that there are 2 dependencies for our server:
The first is listed as a “file:” dependency referring to a file on disk that npm will look for it in the same directory as our server code. This package is required and the setup process will fail if it is not present. This file is the Node.js SDK that allow your server app to talk to the Realm Object Server.
The second is a Node.js module for the Watson service - this will be automatically downloaded for us by the npm - the Node.js package manager.
The Watson API is downloaded for us; the Realm module we can copy from the Realm Mobile Platform distribution that you downloaded.
If you are running a local copy of RMP/PE on your Mac, you copy this either using the Finder or using the Unix cp command - it is in the SDK/node directory of the realm-mobile-platform-professional distribution folder. Just make sure that you copy it to the same directory as your package.json file and that the filename is
realm-1.0.0-BETA-3.0-professional.tgz.
The process for Linux is the same, you will need to copy the same package to your
ScannerServer directory. On Linux systems you will need to get the package from our package distribution system; instructions are included the email you received when you registered to download the Realm Mobile Platform Professional Edition.
This package is the Node.js SDK that your scanner server will use to communicate with the Realm Object Server.
Once you have copied this into place, run the command:
npm install
this will download, unpack and configure all the modules.
In the same directory we will be creating a file called
index.js which is the Node.js application that monitors the client Realms for changes and then reacts by sending images to the Watson Recognition API for processing
The file itself is listed in the code-box below, is several dozen lines long; we recommend you cut & paste the content into the
index.js file you created. Several key pieces of information need to be edited in order for this application to function - the required edits and explanations of what these items do are inline in the file.

Running the Server Script
In order to run the server script you will first need to install the dependencies needed by the application and specified in the package.json file. This is done by running the command
npm install
In the terminal window.
Next, replace edit the
index.js file and replace the
REALM_ADMIN_TOKEN and
BLUEMIX_API_KEY with the your admin token, and the API key generated for you when you signed up for the IBM Bluemix trial.
Once the admin token and API have been edited, run the Scanner server script with the command
node index.js
Once the server starts, the server will be waiting for connections and changes from the mobile clients. Next we will create a iOS or Android simple app that uses this OCR service.
Building the Mobile Client
Completed Scanner Sources for iOS and Android
If you would like to download the completed projects for iOS and Android without working through the tutorial, they are available from Realm’s GitHub account:
https:/github.com/realm-demos/Scanner.git
Scanner for iOS
Prerequisites:
This project uses Cocoapods - to install cocoapods, use the command sudo gem install cocoapods this will ask you for an admin password. For more info on Cocoapods, please see.
Part I - Create and configure a Scanner Project with Xcode
Open Xcode and Create a new, “Single View iOS application.” Name the application “Scanner” and save it to a convenient location on your drive.
Quit Xcode
Open a terminal window and change into the newly created Scanner directory; initialize the cocoapods system type running the command pod init - this will create a new Podfile template
Edit the Podfile (you can do this in Xcode or any text editor) and add the directive
pod 'RealmSwift'
- After the line that reads
use_frameworks!
Save the changes to the file (and if necessary, quite Xcode once again).
From the terminal window run the command
pod update this will cause CocoaPods to download and configure the RealmSwift module and create a new Xcode Workspace file that bundles together all of the external modules you’ll need to create the Scanner app.
Open the newly created
Scanner.xcworkspace file - Use this workspace file instead of the standard
Scanner.xcodeproj file.
Installing the sample image and icon - In order to allow you to run this tutorial in the simulator we are going to download two additional resources. The are linked below - download and unpack the zip file, and then drag each file, one at a time, onto your Xcode project window and allow Xcode to copy the resource into the project. Make sure to check the box “copy resource if needed”.
Setting the Application Entitlements - this app will need to enable keychain sharing and include a special key to allow access to the iPhone’s camera. Click on the Scanner project icon in the source browser and add/edit the following
In the Capabilities section set the Keychain Sharing to “on”
In the info section add 2 new keys to the Custom iOS Target properties: “Privacy - Photo Library Usage Description” and “Privacy - Camera Usage Description” These strings can be anything but are generally used to tell the user why the application needs access to the camera and photo library. When the app is run permission dialogs will be show using these strings when requesting this access.
Application Signing - here you will need to select your team or profile; in some instances Xcode will offer to “fix” this issue for you (i.e., automatically set up any required provisioning profiles),
Either option will be fine. You will be running the application (at least for the purposes of this demo) in the iOS simulator but Xcode may require you to set up the signing details.
With the basic application settings out of the way, we are now ready to implement the app that will make use of the Realm Event handler application you finished previously.
Part II - Turning the Single View Template into the Scanner App
Adding a class extension to UIImage - we will need to add a file to our project with a couple of utility methods that let us easily resize image for display, and to encode them for storage in our Realm database.
Add a new Swift source file called UIImage+Encoding.swift to your project. It can be anywhere in your project’s folders but a convention is to put extensions either in a folder called “Extensions” or with the rest of the project’s implementation files. Add the following code to the file, and the save and close the window.
import Foundation import UIKit extension UIImage { func resizeImage(_ image: UIImage, size: CGSize) -> UIImage { UIGraphicsBeginImageContextWithOptions(size, false, 0.0) image.draw(in: CGRect(origin: CGPoint.zero, size: size)) let resizedImage = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() return resizedImage! } func data() -> Data { var imageData = UIImagePNGRepresentation(self) { // Resize the image if it exceeds the 2MB API limit if (imageData?.count)! > 2097152 { let oldSize = self.size let newSize = CGSize(width: 800, height: oldSize.height / oldSize.width * 800) let newImage = self.resizeImage(self, size: newSize) imageData = UIImageJPEGRepresentation(newImage, 0.7) } return imageData! } func base64EncodedString() -> String { let imageData = self.data() let stringData = imageData.base64EncodedString(options: .endLineWithCarriageReturn) return stringData } }
Creating the Realm model. The model for the Scanner app is very simple; create another new Swift source file to your project, name this one Scan.swift. Copy and paste the text below into the file and save it.
import UIKit import RealmSwift class Scan: Object { dynamic var scanId = "" dynamic var status = "" dynamic var textScanResult:String? dynamic var classificationResult:String? dynamic var faceDetectionResult:String? dynamic var imageData: Data? }
Most of the fields should be self-explanatory. This model will be automatically instantiated on the local device, and then synchronized with Realm Object Server as you take/select pictures and tell the app to scan them.
Updating the View Controller - We are going to replace all of our template app’s boilerplate code with a very simple view that can load an image from the device’s photo library or camera and save this data which causes the object server to scan our sync’d images for text.
Our layout will be simple, yet functional, and when run will look very much like this:
It has 3 main areas: an image display area, a text area to show results, and a status buttons are to select/process an image and reset the app for a new image selection and show the current status of the image processing operation
- Adding in the View setup and display code - Open the ViewController and remove the
viewDidLoadand
didRecevieMemoryWarningmethods (make sure not to remove the final closing brace - this can lead to hard to debug errors).
Adopting the ImagePicker protocol - Near the top of the file - in the class declaration change UIViewController to “UIViewController, UIImagePickerControllerDelegate” this allows to use a picker view to select images; the updated class declaration will look like this:
class ViewController: UIViewController, UIImagePickerControllerDelegate
Next, just after the class declaration, add the following code to declare the UI elements our ViewController will display and the Realm variables needed for the syncing and scanning process:
// UI Elements let userImage = UIImageView() let resultsTextView = UITextView() let statusTextLabel = UILabel() let scanButton = UIButton() let resetButton = UIButton() var imageLoaded = false let backgroundImage = UIImage(named: "[email protected]") //Realm variables var realm: Realm? var currentScan: Scan?
Adding the ViewController lifecycle methods - these take care of setting up and updating the view as part of the application lifecycle (the final method hides the status bar to we can see our images more clearly)
override func viewDidLoad() { super.viewDidLoad() setupViewAndConstraints() } override func viewDidAppear(_ animated: Bool) { updateUI() } override var prefersStatusBarHidden: Bool { return true }
*Adding the autolayout and view management methods& - Near the bottom of the file we’ll add code that sets up and manages these elements. This is a pretty large function with a lot of code that isn’t really relevant to using the Realm Object Server - its job to is to set up all of the views/buttons/etc using autolayout and a couple of utility methods to handle view updates:
// MARK: View Setup and management func setupViewAndConstraints() { let allViews: [String : Any] = ["userImage": userImage, "resultsTextView": resultsTextView, "statusTextLabel": statusTextLabel, "scanButton": scanButton, "resetButton": resetButton] var allConstraints = [NSLayoutConstraint]() let metrics = ["imageHeight": self.view.bounds.width, "borderWidth": 10.0] // all of our views are created by hand when the controller loads; // make sure they are subviews of this ViewController, else they won't show up, allViews.forEach { (k,v) in self.view.addSubview(v as! UIView) } // an ImageView that will hold an image from the camers or photo library userImage.translatesAutoresizingMaskIntoConstraints = false userImage.contentMode = .scaleAspectFit userImage.isHidden = false userImage.isUserInteractionEnabled = false userImage.backgroundColor = .lightGray // a label to hold text (if any) found by the OCR service resultsTextView.translatesAutoresizingMaskIntoConstraints = false resultsTextView.isHidden = false resultsTextView.alpha = 0.75 resultsTextView.isScrollEnabled = true resultsTextView.showsVerticalScrollIndicator = true resultsTextView.showsHorizontalScrollIndicator = true resultsTextView.textColor = .black resultsTextView.text = "" resultsTextView.textAlignment = .left resultsTextView.layer.borderWidth = 0.5 resultsTextView.layer.borderColor = UIColor.lightGray.cgColor // the status label showing the state of the backend ROS Event service or OCR API status statusTextLabel.translatesAutoresizingMaskIntoConstraints = false statusTextLabel.backgroundColor = .clear statusTextLabel.isEnabled = true statusTextLabel.textAlignment = .center statusTextLabel.text = "" // Button that starts the scan scanButton.translatesAutoresizingMaskIntoConstraints = false scanButton.backgroundColor = .darkGray scanButton.isEnabled = true scanButton.setTitle(NSLocalizedString("Tap to select an image...", comment: "select img"), for: .normal) scanButton.addTarget(self, action: #selector(selectImagePressed(sender:)), for: .touchUpInside) // Button to reset and pick a new image resetButton.translatesAutoresizingMaskIntoConstraints = false resetButton.backgroundColor = .purple resetButton.isEnabled = true resetButton.setTitle(NSLocalizedString("Reset", comment: "reset"), for: .normal) resetButton.addTarget(self, action: #selector(resetButtonPressed(sender:)), for: .touchUpInside) // Set up all the placement & constraints for the elements in this view self.view.translatesAutoresizingMaskIntoConstraints = false let verticalConstraints = NSLayoutConstraint.constraints( withVisualFormat: "V:|-[userImage(imageHeight)]-[resultsTextView(>=100)]-[statusTextLabel(21)]-[scanButton(50)]-[resetButton(50)]-(borderWidth)-|", options: [], metrics: metrics, views: allViews) allConstraints += verticalConstraints let userImageHConstraint = NSLayoutConstraint.constraints( withVisualFormat: "H:|[userImage]|", options: [], metrics: metrics, views: allViews) allConstraints += userImageHConstraint let resultsTextViewHConstraint = NSLayoutConstraint.constraints( withVisualFormat: "H:|-[resultsTextView]-|", options: [], metrics: metrics, views: allViews) allConstraints += resultsTextViewHConstraint let statusTextlabelHConstraint = NSLayoutConstraint.constraints( withVisualFormat: "H:|-[statusTextLabel]-|", options: [], metrics: metrics, views: allViews) allConstraints += statusTextlabelHConstraint let scanButtonHConstraint = NSLayoutConstraint.constraints( withVisualFormat: "H:|-[scanButton]-|", options: [], metrics: metrics, views: allViews) allConstraints += scanButtonHConstraint let resetButtonHConstraint = NSLayoutConstraint.constraints( withVisualFormat: "H:|-[resetButton]-|", options: [], metrics: metrics, views: allViews) allConstraints += resetButtonHConstraint self.view.addConstraints(allConstraints) } func updateImage(_ image: UIImage?) { DispatchQueue.main.async( execute: { self.userImage.image = image self.imageLoaded = true }) } func updateUI(shouldReset: Bool = false){ DispatchQueue.main.async( execute: { if (shouldReset == true && self.imageLoaded == true) || self.imageLoaded == false { // here if just launched or the user has reset the app self.userImage.image = self.backgroundImage self.imageLoaded = false } else { // just update the UI with whatever we've got from the back end for the last scan self.statusTextLabel.text = self.currentScan?.status // NB: there's a chance that the currentScan has been nil'd out by a user reset; // in this case just srt the text label to empty, otherwise we'll crash on a nil dereferrence self.resultsTextView.text = [self.currentScan?.classificationResult, self.currentScan?.faceDetectionResult, self.currentScan?.textScanResult] .flatMap({$0}).joined(separator:"\n\n") } }) }
Lastly we will add the code that performs all of the Interactions with the Realm Object Server and the Global Event Listener:
// MARK: Realm Interactions func submitImageToRealm() { SyncUser.logIn(with: .usernamePassword(username: "[email protected]", password: "cinnabar21"), server: URL(string: "http://\(kRealmObjectServerHost)")!, onCompletion: { user, error in DispatchQueue.main.async { guard let user = user else { let alertController = UIAlertController(title: NSLocalizedString("Error", comment: "Error"), message: error?.localizedDescription, preferredStyle: .alert) alertController.addAction(UIAlertAction(title: NSLocalizedString("Try Again", comment: "Try Again"), style: .default, handler: { (action) in self.submitImageToRealm() })) alertController.addAction(UIAlertAction(title: NSLocalizedString("Cancel", comment: "Cancel"), style: .cancel, handler: nil)) self.updateUI(shouldReset: true) self.present(alertController, animated: true) return } // Open Realm let configuration = Realm.Configuration( syncConfiguration: SyncConfiguration(user: user, realmURL: URL(string: "realm://\(kRealmObjectServerHost)/~/scanner")!)) self.realm = try! Realm(configuration: configuration) // Prepare the scan object self.prepareToScan() self.currentScan?.imageData = self.userImage.image!.data() self.saveScan() } }) } func beginImageLookup() { updateResetButton() submitImageToRealm() } func prepareToScan() { if let realm = currentScan?.realm { try! realm.write { realm.delete(currentScan!) } } currentScan = Scan() } func saveScan() { guard currentScan?.realm == nil else { return } statusTextLabel.text = "Saving..." try! realm?.write { realm?.add(currentScan!) currentScan?.status = Status.Uploading.rawValue } statusTextLabel.text = "Uploading..." self.currentScan?.addObserver(self, forKeyPath: "status", options: .new, context: nil) } override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) { guard keyPath == "status" && change?[NSKeyValueChangeKey.newKey] != nil else { return } let currentStatus = Status(rawValue: change?[NSKeyValueChangeKey.newKey] as! String)! switch currentStatus { case .ClassificationResultReady, .TextScanResultReady, .FaceDetectionResultReady: self.updateUI() self.updateResetButton() try! self.currentScan?.realm?.write { self.currentScan?.status = Status.Completed.rawValue } case .Failed: self.updateUI() try! self.currentScan?.realm?.write { realm?.delete(self.currentScan!) } self.currentScan = nil case .Processing, .Completed: self.updateUI() default: return } }
There are 4 key methods here that do the critical work:
prepareToScan()This method creates a new scan object; this is what will be synchronized with the the Realm Object Server
submitImageToRealm()This is where the application authenticates with and logs into the “scanner” Realm. You will need to replace the “YOU USERNAME” and “YOUR PASSWORD” boilerplate with the admin username and password you used when you registered your copy of RMP/PE.
saveScan()This method takes the image that was selected (and shown in the app) and converts it to a data format that can be synchronized and saves it in the Scan object created by prepareToScan(). Once the image is saved, the method sets an observer on the saved Scan object in order to watch for results from the Watson service that is being called by our ScannerServer using the Realm Global Sync Notifier.
observeValueForkeyPath()This method isn’t specific to Realm but a feature of the Cocoa runtime (called Key-Value Observation or “KVO”) that allows observers to be registered to watch for changes in properties of objects and data structures. In this case, in the saveScan() method, we are asking the runtime to notify us when the status of a scan we’ve synchronized changes. When it does, the code reacts by changing the status labels and adding any returned results from the Watson service.
Putting it all together
At the end of the section on Building the Server Application, you created and started a small Node JS containing a Realm Global Sync Listener application that should be waiting for your iOS to connect up and sync images. Now all that’s left to do is fire up your Scanner app and see how this works.
Running the app should be as simple as pressing Build/Run. Barring any typos or syntax errors, Xcode will build the Scanner app and run it in the iOS simulator. Once the app is running, tap the “Tap to select an image…” button, and then select “Choose from Library…”. This will cause the app to use the build in demo image we downloaded when we created the template application. The App should look very much like this:
Once the app has synchronized the image file with the Realm Object Server, the Global Sync Notifier application we created will send the image to IBM’s Watson service. After a moment the results that come back will be displayed in your app:
If you have an active Apple developer account you can run this on real hardware and try it with your own images.
Scanner for Android
Prerequisites: This project uses Android Studio. For more information on Android Studio, please see
Part I - Create and configure a Scanner Project with Android
Open Android Studio and click on “Start a new Android Studio Project”. Name the application “Scanner”. “Company Domain” can be any domain name and “Project location” can be one of convenient locations on your drive. Click on the “Next” button.
The next window lets you select the form factors. Select “Phone and Tablet” and Click “Next”. You don’t need to modify “Minimum SDK” at this time..
The next screen lets you select an activity type to add to your app. Select “Empty Activity” and click “Next”. Because we are going to change layout, you don’t need to select a designed one.
Leave “Activity Name” as “MainActivity”, and also leave “Layout Name” as “activity_main”. Click “Finish” button to complete “Create New Project” wizard. In this tutorial, only one activity is used, and the name is not important.
You can find build script file which named “build.gradle” in two locations. One is on the project root, and the other is under the “app” directory. Modify project level “build.gradle” file on the project root to add Realm dependency, like below. As you see, we add “classpath ‘io.realm:realm-gradle-plugin:2.2.0’” in dependencies block of buildscript. You are now ready to use the Realm plug-in. If you are using higher version of Realm Java, please change the number of plug-in version.
// Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.2.2' classpath 'io.realm:realm-gradle-plugin:2.2.0' } } allprojects { repositories { jcenter() } } task clean(type: Delete) { delete rootProject.buildDir }
Now, we are going to change build script of “app” level. First of all, add “apply plugin: ‘com.android.application’” to register Realm Java dependency. Second, change “compileSdkVersion” and “targetSdkVersion” to 23. Actually, we don’t need those changes for use of Realm Java, but for simple examples. Because the code to fetch after requesting a photo shoot has changed much difficult since API level 24.
apply plugin: 'com.android.application' android { compileSdkVersion 23 buildToolsVersion "25.0.1" defaultConfig { applicationId "example.io.realm.scanner" minSdkVersion 15 targetSdkVersion 23 versionCode 1 versionName "1.0" } …
Since major version of appcompat library depends on API level, we need to modify appcompat library version when target version is changed. The initial value is based on version 25.
dependencies { ... compile 'com.android.support:appcompat-v7:23.4.0' ... }
Now, we need address of server. Add setting code for it in build script. Like below, we get address of localhost which we use for server in this test, and add it to “BuildConfig.OBJECT_SERVER_IP” constant. Items added as “buildConfigField” will be converted to BuildConfig which is a Java object at the time of building app, and added to app.
android { ... buildTypes { def host = InetAddress.getLocalHost().getCanonicalHostName() debug { buildConfigField "String", "OBJECT_SERVER_IP", "\"${host}\"" } release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' buildConfigField "String", "OBJECT_SERVER_IP", "\"${host}\"" } } }
One last thing remains for settings. Add the following code at the end of the “app / build.gradle” file. With this code, we enable the synchronization feature of Realm Java. Without this option, synchronization is not available.
realm { syncEnabled = true }
Part II - Register models and settings
Let’s start to build two models for scanner. One is “LabelScan”, and the other is “LabelScanResult”. When you fill “LabelScan” and pass it to server, the server fills the data in “LabelScanResult” to synchronize. Implement the first model, “LabelScan” as follows:
public class LabelScan extends RealmObject{ @Required private String scanId; @Required private String status; private LabelScanResult result; private byte[] imageData; public String getScanId() { return scanId; } public void setScanId(String scanId) { this.scanId = scanId; } public String getStatus() { return status; } public void setStatus(String status) { this.status = status; } public LabelScanResult getResult() { return result; } public void setResult(LabelScanResult result) { this.result = result; } public byte[] getImageData() { return imageData; } public void setImageData(byte[] imageData) { this.imageData = imageData; } }
Now, implement “LabelScanResult” to hold the result.
public class LabelScanResult extends RealmObject { private String textScanResult; private String classificationResult; private String faceDetectionResult; public String getTextScanResult() { return textScanResult; } public void setTextScanResult(String textScanResult) { this.textScanResult = textScanResult; } public String getClassificationResult() { return classificationResult; } public void setClassificationResult(String classificationResult) { this.classificationResult = classificationResult; } public String getFaceDetectionResult() { return faceDetectionResult; } public void setFaceDetectionResult(String faceDetectionResult) { this.faceDetectionResult = faceDetectionResult; } }
Now, extend “Application” to make “ScannerApplication”. We’ll add code for Realm Java initialization and enable verbose logging:
public class ScannerApplication extends Application { @Override public void onCreate() { super.onCreate(); Realm.init(this); RealmLog.setLevel(Log.VERBOSE); } }
Modify “AndroidManifest.xml” to register “ScannerApplication” to “application” and add two settings for camera.
<manifest package="io.realm.scanner" xmlns: <uses-feature android: <uses-permission android: <application android:name="io.realm.scanner.ScannerApplication" …
Part III - Create layout
Let's first take look at the whole layout file and look at the details.
<?xml version="1.0" encoding="utf-8"?> <FrameLayout android: <RelativeLayout android: <ImageButton android: <TextView android: </RelativeLayout> <ScrollView android: <LinearLayout android: <ImageView android: <TextView android: </LinearLayout> </ScrollView> <RelativeLayout android: <ProgressBar style="?android:attr/progressBarStyleLarge" android: </RelativeLayout> </FrameLayout>
You can see three layouts as children of “FrameLayout”. This includes “RelativeLayout”, “ScrollView”, and “RelativeLayout” in order. The first child, “RelativeLayout” is for view with camera button. The second child, “ScrollView” is a UI layout for the captured image and result. the last one, “RelativeLayout” includes “ProgressBar” for loading.
Part 4 - From single Activity to scanner application
Define constants for server connection in “MainActivity”.
private static final String REALM_URL = "realm://" + BuildConfig.OBJECT_SERVER_IP + ":9080/~/Scanner"; private static final String AUTH_URL = "http://" + BuildConfig.OBJECT_SERVER_IP + ":9080/auth"; private static final String ID = "[email protected]"; private static final String PASSWORD = "password";
We use a constant of random number for buffer size and “onActivityResult”. This constant is assigned a 1000th prime number to just designate it as a sufficiently large and unusual number.
private static final int REQUEST_SELECT_PHOTO = PRIME_NUMBER_1000th;
We use two constants for “onActivityResult”. Those are used to send requests to other activities and to verify the destination when receiving data.
private static final int REQUEST_SELECT_PHOTO = PRIME_NUMBER_1000th; private static final int REQUEST_IMAGE_CAPTURE = REQUEST_SELECT_PHOTO + 1;
Now, let’s define fields in the activity.
private Realm realm; private LabelScan currentLabelScan; private ImageButton takePhoto; private ImageView image; private TextView description; private View capturePanel; private View scannedPanel; private View progressPanel; private String currentPhotoPath; Additionally, define constants and enumurations for "MainActivity". enum Panel { CAPTURE, SCANNED, PROGRESS } class StatusLiteral { public static final String UPLOADING = "Uploading"; public static final String FAILED = "Failed"; public static final String CLASSIFICATION_RESULT_READY = "ClassificationResultReady"; public static final String TEXTSCAN_RESULT_READY = "TextScanResultReady"; public static final String FACE_DETECTION_RESULT_READY = "FaceDetectionResultReady"; public static final String COMPLETED = "Completed"; }
Add code for handling view in
OnCreate method.
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); capturePanel = findViewById(R.id.capture_panel); scannedPanel = findViewById(R.id.scanned_panel); progressPanel = findViewById(R.id.progress_panel); takePhoto = (ImageButton) findViewById(R.id.take_photo); image = (ImageView) findViewById(R.id.image); description = (TextView) findViewById(R.id.description); takePhoto.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if (realm != null) { showCommandsDialog(); } } }); takePhoto.setVisibility(View.GONE); takePhoto.setClickable(false); showPanel(Panel.CAPTURE); … }
Now, it’s time for creating “showCommandsDialog” method and “showPanel” method. “showCommandsDialog” contains “dispatchTakePicture” and “dispatchSelectPhoto” that connect to the camera and the gallery depending on the situation.
private void showCommandsDialog() { final CharSequence[] items = { "Take with Camera", "Choose from Library" }; final AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setItems(items, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialogInterface, int i) { switch(i) { case 0: dispatchTakePicture(); break; case 1: dispatchSelectPhoto(); break; } } }); builder.create().show(); } private void showPanel(Panel panel) { if (panel.equals(Panel.SCANNED)) { capturePanel.setVisibility(View.GONE); scannedPanel.setVisibility(View.VISIBLE); progressPanel.setVisibility(View.GONE); } else if (panel.equals(Panel.CAPTURE)) { capturePanel.setVisibility(View.VISIBLE); scannedPanel.setVisibility(View.GONE); progressPanel.setVisibility(View.GONE); } else if (panel.equals(Panel.PROGRESS)) { capturePanel.setVisibility(View.GONE); scannedPanel.setVisibility(View.GONE); progressPanel.setVisibility(View.VISIBLE); } }
Let’s take a look at “dispatchTakePicture” which opens camera, first. Following code uses “startActivityForResult” to request camera shoot through intent and to get the results back.
private void dispatchTakePicture() { Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); if (takePictureIntent.resolveActivity(getPackageManager()) != null) { File photoFile = null; try { photoFile = createImageFile(); } catch (IOException e) { e.printStackTrace(); } if (photoFile != null) { currentPhotoPath = photoFile.getAbsolutePath(); Uri photoURI = Uri.fromFile(photoFile); takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI); startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE); } } } private File createImageFile() throws IOException { String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); String imageFileName = "JPEG_" + timeStamp + "_"; File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES); File image = File.createTempFile(imageFileName, ".jpg", storageDir); return image; }
Let’s create “dispatchSelectPhoto” which opens gallery. This method is much simpler than previous method because we don’t need to create a file.
private void dispatchSelectPhoto() { Intent photoPickerIntent = new Intent(Intent.ACTION_PICK); photoPickerIntent.setType("image/*"); startActivityForResult(photoPickerIntent, REQUEST_SELECT_PHOTO); }
Add code for synchronization with Realm object server below “onCreate” method. We use “SyncCredentials” to pass authentication information and set “SyncConfiguration” for opening a Realm instance using the previously declared constants. I will skip error handling to make a simple example.
final SyncCredentials syncCredentials = SyncCredentials.usernamePassword(ID, PASSWORD, false); SyncUser.loginAsync(syncCredentials, AUTH_URL, new SyncUser.Callback() { @Override public void onSuccess(SyncUser user) { final SyncConfiguration syncConfiguration = new SyncConfiguration.Builder(user, REALM_URL).build(); Realm.setDefaultConfiguration(syncConfiguration); realm = Realm.getDefaultInstance(); takePhoto.setVisibility(View.VISIBLE); takePhoto.setClickable(true); } @Override public void onError(ObjectServerError error) { } });
Now, add code to close Realm.
@Override protected void onDestroy() { super.onDestroy(); cleanUpCurrentLabelScanIfNeeded(); if (realm != null) { realm.close(); realm = null; } showPanel(Panel.CAPTURE); }
Add code for drawing menu at the top right according to the situation, like following:
@Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.main, menu); MenuItem item = menu.getItem(0); item.setEnabled(false); return true; } @Override public boolean onPrepareOptionsMenu(Menu menu) { final MenuItem item = menu.getItem(0); if (currentLabelScan != null) { final LabelScanResult scanResult = currentLabelScan.getResult(); if (scanResult != null) { final String textScanResult = scanResult.getTextScanResult(); final String classificationResult = scanResult.getClassificationResult(); final String faceDetectionResult = scanResult.getFaceDetectionResult(); if (textScanResult != null && classificationResult != null && faceDetectionResult != null) { item.setEnabled(true); return true; } } } item.setEnabled(false); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { if (item.getItemId() == R.id.refresh) { setTitle(R.string.app_name); cleanUpCurrentLabelScanIfNeeded(); showPanel(Panel.CAPTURE); invalidateOptionsMenu(); } return true; } private void cleanUpCurrentLabelScanIfNeeded() { if (currentLabelScan != null) { currentLabelScan.removeChangeListeners(); realm.beginTransaction(); currentLabelScan.getResult().deleteFromRealm(); currentLabelScan.deleteFromRealm(); realm.commitTransaction(); currentLabelScan = null; } }
Now, let’s create code for sending an image to server when user takes a picture or selects a photo from the gallery. “REQUEST_IMAGE_CAPTURE” is called when user takes a photo, or “REQUEST_SELECT_PHOTO” is called when user selects an image.
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch (requestCode) { case REQUEST_SELECT_PHOTO: if (resultCode == RESULT_OK) { setTitle("Saving..."); final Uri imageUri = data.getData(); try { final InputStream imageStream = getContentResolver().openInputStream(imageUri); final byte[] readBytes = new byte[PRIME_NUMBER_1000th]; final ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream(); int readLength; while ((readLength = imageStream.read(readBytes)) != -1) { byteBuffer.write(readBytes, 0, readLength); } cleanUpCurrentLabelScanIfNeeded(); byte[] imageData = byteBuffer.toByteArray(); if (imageData.length > IMAGE_LIMIT) { BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeByteArray(imageData, 0, imageData.length, options); int outWidth = options.outWidth; int outHeight = options.outHeight; int inSampleSize = 1; while (outWidth > 1600 || outHeight > 1600) { inSampleSize *= 2; outWidth /= 2; outHeight /= 2; } options = new BitmapFactory.Options(); options.inSampleSize = inSampleSize; final Bitmap bitmap = BitmapFactory.decodeByteArray(imageData, 0, imageData.length, options); byteBuffer.reset(); bitmap.compress(Bitmap.CompressFormat.JPEG, 80, byteBuffer); imageData = byteBuffer.toByteArray(); } uploadImage(imageData); } catch(FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { showPanel(Panel.PROGRESS); setTitle("Uploading..."); } } break; case REQUEST_IMAGE_CAPTURE: if (resultCode == RESULT_OK && currentPhotoPath != null) { setTitle("Saving..."); BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeFile(currentPhotoPath, options); int outWidth = options.outWidth; int outHeight = options.outHeight; int inSampleSize = 1; while (outWidth > 1600 || outHeight > 1600) { inSampleSize *= 2; outWidth /= 2; outHeight /= 2; } options = new BitmapFactory.Options(); options.inSampleSize = inSampleSize; Bitmap bitmap = BitmapFactory.decodeFile(currentPhotoPath, options); final ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream(); bitmap.compress(Bitmap.CompressFormat.JPEG, 80, byteBuffer); byte[] imageData = byteBuffer.toByteArray(); uploadImage(imageData); showPanel(Panel.PROGRESS); setTitle("Uploading..."); } break; } }
Finally, make a code that processes an image and returns it on the server-side. This call-back method is registered by “currentLabelScan.addChangeListener(MainActivity.this);” of “uploadImage” method.
@Override public void onChange(LabelScan labelScan) { final String status = labelScan.getStatus(); if (status.equals(StatusLiteral.FAILED)) { setTitle("Failed to Process"); cleanUpCurrentLabelScanIfNeeded(); showPanel(Panel.CAPTURE); } else if (status.equals(StatusLiteral.CLASSIFICATION_RESULT_READY) || status.equals(StatusLiteral.TEXTSCAN_RESULT_READY) || status.equals(StatusLiteral.FACE_DETECTION_RESULT_READY)) { showPanel(Panel.SCANNED); final byte[] imageData = labelScan.getImageData(); final Bitmap bitmap = BitmapFactory.decodeByteArray(imageData, 0, imageData.length); image.setImageBitmap(bitmap); final LabelScanResult scanResult = labelScan.getResult(); final String textScanResult = scanResult.getTextScanResult(); final String classificationResult = scanResult.getClassificationResult(); final String faceDetectionResult = scanResult.getFaceDetectionResult(); StringBuilder stringBuilder = new StringBuilder(); boolean shouldAppendNewLine = false; if (textScanResult != null) { stringBuilder.append(textScanResult); shouldAppendNewLine = true; } if (classificationResult != null) { if (shouldAppendNewLine) { stringBuilder.append("\n\n"); } stringBuilder.append(classificationResult); shouldAppendNewLine = true; } if (faceDetectionResult != null) { if (shouldAppendNewLine) { stringBuilder.append("\n\n"); } stringBuilder.append(faceDetectionResult); } description.setText(stringBuilder.toString()); if (textScanResult != null && classificationResult != null && faceDetectionResult != null) { realm.beginTransaction(); labelScan.setStatus(StatusLiteral.COMPLETED); realm.commitTransaction(); } } else { setTitle(status); } invalidateOptionsMenu(); }
Now, you’ve successfully created an Android app that takes a image or select it to recognize images through the Realm Object Server. Please refer to for the entire example. | https://realm.io/jp/docs/tutorials/scanner/ | CC-MAIN-2018-05 | en | refinedweb |
WS-Reliable Messaging and Session Support (Part3)
Posted by bhaktimehta on June 7, 2007 at 10:23 AM PDT
This is the third part of tri series blogs where in Part 1 we showed
one way
of supporting sessions with
WS Reliable Messaging. Mike showed in hisblog
WS Reliable Messaging and Session Support Part 2
what are the
problems with this approach and we now
conclude with a third part where we have tried to fix some of these
problems .
Sessions are unique
ids used to identify a client. They would help
maintain state for each client.
In this sample you will see how
sessions can be supported with WS Reliable Messaging (WS RM) .
WS
RM is one of the
enterprise features in ProjectTango
which is Sun'sJava Web Services
interoperability project with Microsoft's
Windows Communication
Foundation (WCF).
The following snippets of code show how the JAX-WS Endpoint
implementation which is RM enabled
supports sessions .
This is the
wsdl which shows RM is enabled in the endpoint by the presence ofWS-RM
Policy Assertions.
Here is endpoint implementation class
@WebService(endpointInterface="rmdemo.server.RMDemo")
public class RMDemoImpl {
....
}
As shown in part 1 JAX-WS uses annotations defined by Common
Annotations for the Java
Platform (JSR 250),
to inject the Web ServiceContext and declare lifecycle methods. Web
ServiceContext holds the
context
information pertaining to a request being served. With JAX-WS Web
Service all you need to do is
mark a field or method
with @Resource. From the WebServiceContext,MessageContext
pertaining
to the the current request can be accessed.
@Resource
private javax.xml.ws.WebServiceContext context;
As mentioned above WebServiceContext exposes theMessageContext
for the request being served when this method is called .
The session
is obtained from the MessageContext using a jax-ws property
"com.sun.xml.ws.session"
private Hashtable getSession() {
return (Hashtable)context.getMessageContext()
.get("com.sun.xml.ws.session");
}
The following getter method returns the String associated
with each request .
Correspondingly the setter method
stores the Strings for each session in the
HashTable respectively.
private String getSessionData() {
Hashtable sess = getSession();
String ret = (String)sess.get("request_record");
return ret != null ? ret : "";
}
private void setSessionData(String data) {
Hashtable session = getSession();
session.put("request_record", data);
}
These addString method and getResult method are exposed by our RM
endpoint and are same as Part 1 .
The method addString takes a
String
as entered by a user and adds it to the Strings stored in the session
data for that session.
The getResult will return all the strings entered by the user during
that session. @WebMethod public void addString(String s )
setSessionData(getSessionData() + " " + s); } @WebMethod public String getResult() { return getSessionData(); }
Full source code for theRMDemoImpl.java
is here.
Advantages
Here the Session is created every time a new CreateSequence request is
received and gets terminated everytime there is a
TerminateSequence
request. This way the resource management issue as mentioned by Mike is
addressed.
Client CodeHere
is the source code for the client. The client enters various
input Strings and finally hits carriage
return to terminate the client application and all the Strings received
so far for that client will be returned by
the
server.
Sample will be bundled in the wsit workspace and this is
theREADME
to run the samples.Additional sources of information

Hi John,
Where you able to solve this one?
I'm having the same problem.
Thanks in advance,
Tzach
Back from the dead thread here - I don't know if the OP ever solved this, but the issue is that the format returned is not what Zenoss is looking for.

Hi jmp242,
Thanks for replying.
I have found my scripts are getting the return code 1 ( General error ) when I use the logging.basicConfig function in my scripts.
When I mask them, zencommand run myscripts perfectly with return code 0 - Success.
I've developed my scripts with python 2.7 and I see zenoss is using python 2.6.2, maybe logging.basicConfig isn't supported by python 2.6.2?
Thanks in advanced for any help
Tzach
basicConfig has been around a while, it should work just fine in 2.6.2. I actually use it in many of my dmd scripts (albeit I've not tried it in a command data source, but I can see why it would make a difference).
Are you sure you are properly using the basicConfig method? If you create a simple .py file with a main, and you run it, what is the exit code as seen by the OS?
Hi Dpetzel,
Thanks for the response
Here are both the script and result in zencommand debug.
Notice the return code of zencommand.
am I doing something wrong?
This is the check.py:
#!/usr/local/zenoss/zenoss/bin/python
# Logging configuration
import logging
# change this to logging.DEBUG for more information
logLevel = logging.INFO
logname='check'
logger = logging.getLogger(logname)
formatString = '%(asctime)s - %(name)s - %(levelname)s - %(filename)s - %(funcName)s - %(message)s'
logging.basicConfig(filename=logname, level=logLevel, filemode='w', format=formatString)
consoleLogger = logging.StreamHandler()
consoleLogger.setLevel(logLevel)
# create formatter
formatter = logging.Formatter(formatString)
# add formatter to console
consoleLogger.setFormatter(formatter)
print "COMMAND OK|test=1"
This is the zencommand debug log:

You'll need to pass an exit code.
import sys
sys.exit(0)
Best,
--Shane (Hackman238)
Hi Shane,
I added sys.exit(0) at the end of the script.
Still, zencommand return with exit code 1
2012-03-27 09:47:38,168 DEBUG zen.zencommand: Next command in 160 seconds

Tzach:
Really? Thats bizarre. Is anything in the script failing?
--Shane
Hi Shane,
1st, Thanks for replying
2nd, nope, nothing else is failing...
The problem is I can't debug why it return the exit code 1.
From what I have found out the zencommand.py is executed using twisted module.
The function that recieve the return code is:
def processEnded(self, reason):
"notify the starter that their process is complete"
self.exitCode = reason.value.exitCode
log.debug('Received exit code: %s' % self.exitCode)
log.debug('Command: %r' % self.command)
log.debug('Output: %r' % self.output)
This function is located, at least in my install here:
/usr/local/zenoss/zenoss/Products/ZenRRD
BTW, this an ubutnu server and zenoss installed on it.
Tzach:
Try passing an arbitray code like 42 or 75. See if the code is passed correctly. This is very interesting.
--Shane
Shane:
It seems sys.exit doesn't matter to the zencommand, I get the same result.
Meaning if the script has the line:
logging.basicConfig(filename=logname, level=logLevel, filemode='w', format=formatString)
Then I get following:
2012-04-01 10:13:15,126 DEBUG zen.zencommand: running '/usr/local/zenoss/scripts/check.py'
2012-04-01 10:13:15,126 DEBUG zen.zencommand: cmd line: '/bin/sh -c exec /usr/local/zenoss/scripts/check.py'

2012-04-01 10:13:15,227 DEBUG zen.zencommand: Received exit code: 1
If I mask the logging.basicConfig with # like this:
#logging.basicConfig(filename=logname, level=logLevel, filemode='w', format=formatString)
I get the following:

Interesting. I'm going to tes this in other versions monday and get back to you. Looks like a bug.

Tzach, I was able to recreate a similar sitation if permissions on "check" (The file) don't have write permissions. Is it possible that the "check" file doesn't have permissions for the zenoss user to write/append?
In my attempts to reproduce, I ran the check.py first as root, then switched to the zenoss user and manually ran check.py. In this case I did see a stack trace (unsure if zencommand might swallow it), but I did get an exit code of 1.
It might be worth checking the permissions.
Hi Dpetzel, Shane,

THBK1-10 is a cheap dual system (Android 4.2.2 /Windows 8.1) tablet based on Bay Trail (Intel Atom Z3740D). More details
I'm trying to hack it, and especially get root and use non-signed zip in recovery. Basically i'm stuck at theses points, and i'm requesting directions to continue the work.
I have posted in W8 section, but obviously, this is no longer the place
General
------------
* i can use a work-around to write system (/system, /data) partitions
* i can flash signed updates via recovery
* google apps are working flawesly. Only thing is to keep original files (stock keyboard and layout)
-> i would like to flash non-signed zip via recovery, but i guess i have to build a custom recovery, or can i exploit something else ?
Root:
-------
* no auto root is working (z4root, towelRoot). Regarding towelRoot, i tryed each 8 common parameters, and i don't really know how to do others. I have also heard this is only working in 4.4.2+
* pushing su is not working. When i'm launching it, let's say from terminal, i have a code 255 return (-1). Tested with both arm and x86 version (i'm still wondering why arm su is also returning -1, i would have expect a non valid binary. Or perhaps my x86 version is bad ?
-> i'm still trying to dig this issue, and idea on how i could do ? i believe running SU was enough... but it seems not. Any idea ?

I'm attempting to wrap my javascript/html application using qt and so far everything works fine, however scrolling is unbearable. On both Windows and OS X when scrolling it appears as if it takes several seconds for the scrolling to carry out. It is especially sluggish when I'm attempting to scroll through a DIV where its contents was computed dynamically with javascript (sometimes I scroll, count to ten, and it's stil trying to compute what to do). Even if I run something like this, though:
@// import QtQuick 1.0 // to target S60 5th Edition or Maemo 5
import QtQuick 1.1
import QtWebKit 1.0
Rectangle {
id: application
width: 1014
height: 500
WebView {
id: page
html: "<iframe src=''></iframe>"
preferredWidth: parent.width
preferredHeight: parent.height
scale: 1.0
settings.localContentCanAccessRemoteUrls: true
}
}

I'm hoping there's a fix for this, my qt experience other than with this has been wonderful! | http://forum.qt.io/topic/16506/very-very-poor-scrolling-using-qtwebkit | CC-MAIN-2015-18 | en | refinedweb |

"Why would we be looking for rocks?" Inverness Primary School teacher Gail Bockiaro asked her students before their rock scavenger hunt Her third-grade,class has teamed up with a Citrus High School chemistry class for a school science fair project on rocks. "When you find your rock, you are going to find your new best friend," Bockiaro joked with the class. Chemistry II teacher Kevin Bingham had his class hide sedimentary, igneous and meta- morphic rocks on Citrus High's football field and track for the third-graders. Each student wrote directions so the children could each find a rock Gina Russo, 8, and Chris Ramirez, 17, were the first pair to find the rock Chris hid. His directions sent Gina crawling under track hurdles and jumping into the sand pit When Gina saw it she exclaimed, "It's a girl!" She named her rock Teresa. Next week the elementary school students will visit Bingham's class again to classify the rocks they found and perform experiments to find the rocks' hardness, weight, mass, and what minerals are inside. "It's fun just getting out of the classroom and playing with the kids," Chris said. Bockiaro said the rock experiment benefits the children in several ways. It gets the younger children excited about science in high school, while teaching them important Sunshine State Standards.

"It's real non-invasive," Deutschman said. "You don't want to be tested don't join the baseball team." The topic came up as school board members discussed changes to the 2005-06 Student Code of Conduct Deutschman said that when she and Superintendent of Schools Sandra "Sam" Himmel nmet with high school students in January to get feedback on the Code of Conduct, a student thought steroids should be specifically mentioned. Drugs in general are banned from schools under the blanket term "controlled substances," director of student services Renna Jablonskis said. She explained the district does not have a method for drug testing students, but if a student is arrested the district can request the student be test- ed. Jablonskis researched Hernando, Marion and Polk counties to see how their dis- tricts address steroids and learned Polk is the only one of the three that tests athletes for -drugs. Deutschman said it is too late to make changes regarding steroid or drug testing for the upcoming school year, but said she would like more research on the cost of drug-testing stu- dent athletes. School board member Bill Murray explained the danger of steroids to a child whose body is still developing. He said the strain the athletes put on their bodies by using steroids could cause perma- nent health issues. "No one talks about that," Murray said. "They just talk about 'bulking up.'"

A deputy responded to a Beverly Hills home in reference to a distur- bance. morning from Magrino and Lewan. In one request, Magrino asked Couey to pro- vide DNA samples so investiga- tors can compare bodily fluids collected ai the crime scene, including clothing and other evidence gathered. In another motion, Magrino is also asking for writing sam- ples from Couey to compare with evidence gathered, indi- cating "there is a reasonable basis to believe that the hand- writing exemplars will estab- lish the defendant's connection with the case." Magrino could not elaborate because the evidence has not been given to Lewan. !. .. v "* , A 73-year-old woman told the deputy she was "extremely afraid," and that Lank choked her, twisted her arm and made threats to her, according to the report.

Patricia Thomas requesting- that all evidence be sealed relating to a search warrant, inventory and other evidence' taken from the Lunsford home, until further notice. In the meantime, Magrino stressed the importance of let: ting a jury decide the cased, rather than letting the extra" publicity the case is receiving, interfere. "The bottom line is, with all due respect to the media," h" said, "what's important to us is' to try the case with the 12 peo- ple from the community." v .i JHRONICLL rordWis Best CoM Rit y Newspaper Serving Florld's 8,st Commtnity mall: In Florida: $59.00 for 13 weeks Elsewhere in U.S.: $69.00 for 13 weeks To contact us regard your seronline.com Newsroom: [email protected] Meadowcrest office 44- 1624 N.

DOG Continued from Page 1A In between laundry and ba k- iog homemade cookies for relief workers, Chipkar volun- teered her time at the animal shelter bathing and caring for tlOe homeless dogs. i That's where her heart melt- ed. Of the more than 350 lost dbgs, Chipkar put her name on at least a dozen she would've taken them all if she could. , But she couldn't, so she took hpme Charlie, a brown cocker spaiel the same "bro\Mil cocker" she had seen come in afl matted and ugly. He had hgd worms and still has a heart murmur; his coat had been so matted that the volu n- tier groomers shaved him completely bald. SChipkar didn't care. "I just wanted to bring him home and adid to the menagerie," she soid. "I just wanted to give hi m ai better home (than the shel- ter)." ,She hadn't thought about t aining him for anything spe- cial. But during an Interfaith Council program that featured bonnie Saylor from Hospice, POLICE Continued from Page 1A and burglaries jumped slightly from 21 in 2004 to 23 ii 2005. i During those three months, Inverness' arrests more than doubled from 91 in 2004, to 11 in 2005. Likewise, Inverness citations nearly quadrupled from 301 in 2004, t4 1,178 in 2005, and traffic accidents dropped from 140 in 2004, to 112 in 2004. "You get what you pay for," Alexander said. "The quality of service they are getting is better." , Alexander and Rouch agree that the handover also has benefited former IPD officers. : "We've received more pay raises, here, than we did the last five years there," Alexander said. 1Along with bigger salaries, better training, better hours, less stress, more manpower and better resources all come t4 mind, Alexander said. I Just ask Rouch how he feels about the Sheriff's Office crime analysis unit and watch hWs eyes light up. : "They are so thorough... it's really exciting," Rouch said. "t's a very aggressive unit." i ALL ABOUT PUPS PUPS (Pets Uplifting People's Spirits) is part of Hospice of Citrus County's volunteer department. Volunteers receive Hospice orientation training to become familiar with: the his- tory and philosophy of Hospice, the history of Hospice of Citrus County, patient and family rights, loss and grief and confidentiality and HIPAA laws. The dogs are "interviewed" and screened on their ability to handle situations such as: accepting a stranger, sitting polite- ly for petting, good appearance and grooming, walking on a leash, walking through a crowd, sitting and down on com- mand coming when called, not reacting to other dogs, ani- mals or situations and working with a person other than their owner. B When the dogs pass the screening, they are referred to Therapy Dog international (TD!) for certification, which quali. fies them to be covered by insurance while they are working. Dogs also receive the AKC Good Citizenship Test. Dogs do not need to be purebred, but need to be in good health and have required vaccinations. Hospice accepts dogs that have been certified by other groups that certify pets; if they are not certified, Hospice uses TDI. H Once the dogs are certified, they visit patients in local nurs- ing homes, and not just Hospice patients. When Hospice House opens in November, the PUPS will make regular visits there to patients and families. Currently, Hospice has three PUPS dogs: Charlie (Joan Chipkar, owner), Bailey (Howard Watson, owner) and Lady Buff (Mike Stokely, owner). For information about the PUPS program, call Bonnie Saylor, Development Director, Hospice of Citrus County, at 527- 2020, Ext. 263. she heard of the PUPS pro- Chipkar started thinking gram. about Charlie's gentle nature The quality of service they are getting is better. - Deputy Lee Alexander former chief of the Inverness Police Department, about joining the Citrus County Sheriff's Office. The crime analysis unit, which serves as a massive information source for inves- tigations, was one of many resources unavailable to Rouch at IPD. "There's so much we want- ed to do that we just couldn't," Alexander said. "And that's hurt the community. They lose out." At IDP, there was only one detective, usually "tied up" with the department's case- load. At the Sheriff's Office, Alexander is one of 22 detec- tives, and the same "struggle doesn't exist." In early March of 2004, Sheriff Jeff Dawsy promised IPD officials, Inverness lead- ers and residents top-notch policing, better services and more law-enforcement resources. He wasn't kidding, Alexander said. But there's something Alexander misses most about IPD, and that's the "close- knit" feeling of a small agency. "This agency is so big, you just can't get to know every- body," he said. But when times get rough, he knows his new family at the Sheriff's Office will be there. "Even though you don't know anybody, people come out of the woodwork to help out," Alexander said. "Simply because you're a member of this family." Lt. Buddy Grant, eastside district commander, said he's pleased with the transition and the way former IPD offi- cers are adjusting to their new responsibilities at the Sheriff's Office. "They've mixed in well with 'Funeral d-tome 'WIl, Crematonr Bertha Wilbur Call for Information Joseph Caulfield, Sr. Private Cremation Arrangements Warren A. Schoen Private Cremation Arrangements 726-8323 and the way he was at the same time lively, yet calm. She thought he might make a per- fect service dog. After meeting with Saylor, Charlie went through Hospice training, passed it and was cer- tified. He now wears a red bandana with his name embroidered on it, which identifies him as a certified service dog and enables him to go to nursing homes and hos- pitals. "My cousin has terminal cancer, so I took Charlie to practice on him," Chipkar said. "My cousin couldn't do much, and he was in so much pain. But he would pet the dog and he would smile. Even when Charlie would lay down, I would see (my cousin) watch him and I'd see him smile." During a visit to the veter- ans' hospital in Tampa, Chipkar inquired about bring- ing Charlie there and learned he would be most welcome. "I was talking to some men sit- ting in the lobby and they all started telling me their dog stories 'I had a dog once.' "I know if you put me in a nursing home or hospital and brought in a dog and let me pet it, it would be the happiest day of my life. Even on your worst day, if I feel down or some- thing, just watching animals makes you smile." Chipkar believes Charlie was made for this. During his training, he proved to be a nat- ural. He follows commands without the aid of treats. Hugs and kisses are the only "treats" he seems to desire or need. "Not all animals are suited for this," Chipkar said. "When I first found him, I thought he was just a 'dog' dog. I just wanted to bring him home. But I believe that God does things in my life that are right. Out of the 350 dogs there, I could've gotten any of them, but I got this one. "If you could've seen how my cousin reacted to this dog!" she said. "I'm new at this, but I know that when I take him places and especially where there's children he calms them down. "It's strange how things work out," she said. "Everything just fell, ilnto,. place. It just seems he was made for this." our current officers," Grant said. "I've been very happy with the level of professional- ism from the officers who've come over" IOne FREE Month of Service* :Quality Call now for our 2005 Specials ult LAWN CARE & LANDSCAPE CUSTOM WATER GARDENS & PONDS P property OFFERING PER-CUT AND MONTHLY CONTRACT RATES Services The last call you \ill ever have to make for quality Services property services [L FREE EST.

Curt Ebitz .......................... citizen member Williamson Mike Moberley ....................guest member 'You may differ with my choice, but not my right to choose." D- svid S. Arthurs publisher emeritus MISSING THE MARK President's grant program unrealistic resident George W. Bush has a plan to make com- munities better by making them suffer The plan is that if the children in a community don't come up to snuff in meeting the require- ments of the President's Leave No Child Behind plan, he intends to institute a tough-love approach to communities across the United States by withholding government grants. This approach would offer jus- tification for feder- al funding cuts already proposed THE IS in the President's THE I budget package. City grant Since the Pres- to educ ident is already proposing an esti- OUR OP mated $3.2 billion it won't slash in grants to Florida's local gov- ernments and a $392 million cut from "Strengthening America's Communities" block grants over the next five years, poor school performance in No Child Left Behind would be a ready-made reason to makethose cuts. Just to put this .into perspec- tive, since 1997, the City. of Inverness alone has competed for and won $2.6 million in grants that helped with down- town redevelopment, housing, rehabilitation grants and eco- nomic development. States, including Florida, set their own standards for school performance. State educational administrators in Tallahassee No plea bargains s Today's front page of the Chronicle, our state attorney's office plea-bar- gained aman that molest- ed children two little I . girls under' 5-to an,11- year sentence instead of life ir. prison. They want to CALL do the same with the lady 5 schoolteacher that assault- 563- ed the young boys. She probably won't even get any jail time. Instead of the petition that's being passed around to make it tougher on finding child molesters and keeping them under security after they're caught, we need to pass one to have the state attorney and the judge removed from their positions. There should be no plea bargain. These people should go to jail for life. Educators first This is in response to "Pay for coaches." You asked the questions; let me answer them. First of all, the majority of coaches in Citrus County are educators first, coaches second. That's right, the math, science and English teachers you speak of are also your coaches who coach on a supplementary basis. These coaches sacrifice much more than you realize long hours at work, working weekends and holi- days- simply to see student ath- letes learn and grow as individuals. They certainly do not do it for the money. A football coach, by the way, is paid much less than a first-year teacher. As any good educator will tell you: get your facts-in order first before you make an argument. must have been tempted to lower their self-imposed bar if only to grade higher on the fed- eral rating scheme. After all, a lot of money is at stake, even though a downward adjustment would have worked against the improvement of edu- cation in Florida. Florida stood firm and didn't lower the bar, but the risk is great. Consider that last year, less than a quarter of Florida's schools met federal guidelines. If our schools show similar results next SUE: year, if the Bush Administration plan s linked becomes reality, the ation., damage could be considerable. INION: The symmetry in work. this plan would be elegant if it were based in reality, but it isn't. This experi- ment in social engineering, link- ing school performance to feder- al grants to towns and cities, is based on a false premise. Great improvements in education require vision, not implied threats. The carrot and stick approach to make our educa- tional system better is a short- sighted one. This scheme put forward by the President is demeaning to all of us who are working earnestly to improve our com- munities and our schools. It appears that the President is adopting the role of a stern par- ent who will only let us drive the family car if we get good grades. N Missing Wooten Where, oh where is our good-old former commis- sioner, Josh Wooten, when we need him? Since Josh has been put out of office by those who didn't think \he was doing a good job I thought he was doing 0579 an excellent job our 0579l roadsides look like trash heaven. At least when Josh was there as commission- er, our roadsides looked clean. He had people out cleaning up almost every day. Name the towns This is for the Weather Channel: When you give the name of a coun- ty where you have a tornado or bad storms, give the name of the town. We have loved ones in those areas and we also would like to see what town it's in. Remove signs This is to the article regarding religious drivers. If the drivers are flipping you off and running you off the road and cursing at you, they are not Christians. So they must take those signs off their car because a Christian would not flip somebody off or run them off the road.

We want them placed where they will never put our kids at risk again. The idea of releasing this scum back into society to kill time and time again must stop once and for all, without fail. Thousands of our children are abducted every year and only one out of seven are located. I'm sure we can improve on this statistic. I want our children to be safe on our streets and in our homes. I guess that I want my government to keep the evil things out of reach, putting them in harms way in the first place. Gaylord LaGraves Homosassa Liberal label Hugh S. McMurdo writes: "The tragedy in America is that liberalism has captured the once-great Democratic Party of President Andrew Jackson.

Franklin Delano Roosevelt, our most patrician president, was called" traitor to his class because he chose to champion the many in need instead of the privileged few who :, were his peers. - His administration crafted pro- grams to feed the hungry, employ the. jobless, educate the children and assure that the elderly would not live4 their final years in abject poverty., These programs were examples ofF blatant Democratic liberalism.

The Hurricanes proved worthy of their nickname as they wreaked havoc on the host Panthers. Citrus erupted for an 11-run second inning as it mercy-ruled Lecanto 17- 0 in five innings. It. didn't matter where Lecanto (3-8, 1-5) pitchers put the ball Citrus (8-6, 4-2) just kept connecting anyway, fin- ishing with 12 hits. The mercy-rule win was Citrus' second in as many days. On Thursday, the Hurricanes routed visiting Hernando 15-3. "It's nothing I'm feeding them," Citrus coach Jon Bolin laughed. "They're just swinging the bats real well and getting good pitches. They're starting to be a little more .selective, but aggres- sive when they need to be." Even when the Hurricanes weren't making solid contact, they found themselves reach- ing safely on account of the eight errors Lecanto commit- ted in the field. The Panthers just couldn't get themselves out of trouble. They missed throws, dropped fly balls and booted groundballs. "We were a little short- handed tonight," Lecanto coach Bruce Sheffield said. "We've got some kids hurt, sick and we had a young man who made a poor decision in school so we had to sit him tonight We had to move some people around.

Jeff Oleson came to bat next and took a 1-1 pitch to right center- field for a double that scored pinch runner Mike Devary and Padgett to cut Crystal River's lead to 6-4. After a visit to the mound, it was ruled that Bayer had to be pulled because the Pirates had exceeded their allotted visits to the pitcher's mound that inning. Cummins came in and got Johnson to ground into the inning's second out, but Ketchum scored on the play to pull the Leopards within 6-5. With Oleson on third, Cummins issued a walk to Eric Neal, who stole second a batter later to put a pair of runners in scoring position. But Cummins diverted disas- ter by securing the final out Crystal River (7-5) had jumped out to a 4-0 lead after four innings by capitalizing on walks and wild pitches thrown by Leopards' Johnson. The lead could have been substantially more but the Pirates left 15 run- ners on base, including leaving the bases jammed in the first and fifth innings. -A --- -. .- m .0.. - --m. 4Mb.- b. .. a . -b .. . - S - . .- . --d - - a e. e --Availabld Available from Commercial News Providers *.-0 - -rn-.~ - -w - - - 0 ~ ~.- - 0 20.

Joey Budnick popped out and then things.got out of hand. Lecanto catcher Herbie Sickler tried to throw out Van Gorder attempting to swipe second, but no one was on the base to cover the throw. Anthony Delguidice then brought Van Gorder home with a double, and was brought home himself on a double by Randy Hernandez. Matt Lehman followed by popping up to shallow left field, but a trio of Panthers seemed to be confused as to who should field the ball and let it drop. Hernandez scored and Lehman advanced to third on a single by Nick Delguidice, who took second base on the throw. Hudak hit the next bat- ter, Mark Xenophon, to load the bases. McPherson followed and hit a routine grounder to short- stop, but the throw was dropped at second base, allow- ing him to reach safely and Lehman to come home.

"Some players don't like the pressure when runners are on base, but I thrive on it I seem to be able to focus well in that situation." Citrus played well, but fell victim to its oWn mistakes. "I think we actually out hit them, but you wouldn't know it by the score" Hurricane coach Mike Reynolds said. "Overall, I think our girls played very well." Citrus settled down late in the game after falling behind early Hurricane pitcher Jillian Couillard sat down nine bat- ters in a row and faced only 10 total Pirates batters in the final three innings. Couillard was sharp with the bat as well, going 2-for-3 for the night, with an RBI in the sixth driving in the Hurricanes first run.

Four successive hits scored three quick runs, putting the game away for the Pirates.

Musical group feels there's room for both NANCY KENNEDY [email protected] Chronicle Matthew Smith remembers singing praise songs as a teen and feeling mis- erable. "I used to lead worship in high school for my youth group, but always felt inadequate as a worshipper," he said. "I never seemed to be able to stir up the kind of emotions in myself that I saw in others, or that I imagined should accompany worship through song." It wasn't until after he graduated col- lege and was introduced to old hymns put to new music that he discovered worship in the way he had always want- ed to experience it. Now, as lead singer of the Indelible Grace touring band, and one of the vocal artists on the Indelible Grace albums, Smith is part of what he calls' the "new hymns movement," which joins old hymns with new music. Smith and the Indelible Grace band will be in concert at 7 p.m. Friday, April 7, at Seven Rivers Presbyterian Church in Lecanto. Admission is $6 for adults; students are free. They will also be in concert at 7 p.m. Saturday, April 9, at amum n 0. nn. ,- mm 'om -m u __lmm_, _fm 40 0 f lmmwm_ wo w & so4 - -.0w/OP .t a -m /-/ll- IE~~ ~ Good Shepherd Presbyterian Church, 151 S.W 87th Place, in Ocala. The Indelible Grace CDs contain such classic hymns as "Come Ye Sinners," "What Wondrous Love is This" and "Praise My Soul the King of Heaven." Smith said he's not "anti-praise songs," but he does contend that wor- ship leaders need to be discerning in their song choices and "sensitive to the realities of their congregations."

She's the one who convinced me to go with her to do laundry for hurri- cane relief workers after Hurricane Charley de- stroyed central Florida last year. I had gone just that one time, but Joan went back repeatedly. Joan has one of those kind hearts that I only dream of having. I'm hoping if I spend more time with her that some of her kind- heartedness will rub off on me. Joan has never met an ugly dog. There's no such thing as a stray as.long as she has four walls and a roof. She likes people, too she adopts those as well. During one of her laundry trips last fall, Joan wan- dered over to the makeshift animal shelter and put her name on about a dozen or so dogs to take home in case their owners didn't claim them. She ended up with Charlie, named after the hurricane that left him homeless, Charlie is a brown and white cocker spaniel; only when Joan first saw him, he was mostly a ball of matted fur and flea bites, Please-see GRAC/Page 7C -N M-"mm a. lb .M Il *40% MWOOM -Al P&qA- Copyrighted Material Syndicated .Content I~ ~ ~ rn v'~~ I T Available from Commercial News Providers .t, .

L Man's efforts to evade his personal responsibility for sin did not begin in thi4 decade, nor even in the previous century. From the time of the first transgression, man has tried to blame someone also for his own sinful condition. When Goa" asked Adam if he had eaten of the forbidden tree, Adam immediately implicatedX two others as being responsible for his sin. "The (1) woman who (2) Thou gave to be with me, she gave me of the tree, and I did eat" (Genesis 3:12). The womait gave him the forbidden fruit, and God gave him the woman! It's not myfaulti God thought differently. Early theologians picked up this erroneous "It's-not-my-fault" mentality and, systematized it. If it's not my fault that man sins, it must be somebody's fault so blame it on Adam. They falsely concluded that because man is a descendent oP Adam, man is born totally depraved and guilty before God from birth. As a result1 of this inherited depravity, man is simply not able to overcome sin and practiced righteousness. This man-made doctrine goes on to teach that man must receive some direct of miraculous operation of God (via the Holy Spirit) to enable him to choose to do good. Man's conversion, therefore, rests solely upon the shoulders of God. The consequence of this teaching is obvious: If I have not received th, gospel and been converted it's not my fault! The teaching of the Bible, however, is fundamentally different. From the days of the garden, man was created with volition (the power of choosing) and held accountable for his decisions (Genesis 2 and 3). There were two basic influences affecting the decisions of the man and woman, and they willfully yielded to Satan's influence rather than to God's. r Who can receive the gospel and be converted? The false doctrines teach that maidr has no choice in this matter It is the sole responsibility of God. The Bible teaches, however, that man does indeed have a choice, and shares in the4 responsibility of his salvation. God's grace was expressed through Jesus Christ$ and is the means of power of salvation. This is God's free gift to man (Romansi 3:24; 5:15). Sinful man could never, if left to himself, find his way back to God0 (Jeremiah 10:23; Romans 3:10-18). God, therefore, graciously provided the way of salvation, and seeks to persuade men to place their trust in Him (Romans 1:16; 1 Corinthians 5:11) Who can receive the gospel and be converted? "Whosoever will, let him take thij water of life freely (Revelation 22:17)." What about the man who has morp confidence in himself than he has in God? Or the man who chooses not to listen. to God, and will not yield to God's direction and instruction? He obviously cannot receive the gospel and enjoy redemption in Christ. He cannot blame God, however, for his spiritual tragedy. It was his choice to make. What about the man who chooses to listen to God and yield to the words of inspiration? This is th- man of whom God said, "I will put my laws into their mind, and on their heaird also will I write them" (Hebrews 8:10). This is the man who can be saved b}6 grace through faith (Ephesians 2:8). Who can receive the gospel and be saved? The man who chooses to accept God's grace. Whosoever will. Because of our conviction regarding man's volition in this matter, we preach the Gospel and encourage men and women everywhere to makl their choice for God.

In other words, I felt obligated to give God glory, because mentally I knew he deserved it, but it never sprung from being overwhelmed at who God is or what He has done. In the same way, I want- ed to be renewed but wasn't being renewed, which led me to believe that I wasn't doing things right It was a mess."

"It was just procrastination and overload, as I explained to my con- gregation," Miles said.

Miles said. his wife, who normally did their taxes, was involved in two Smith said he wants to see people get past the idea of wor- ship as singing only, or even that true worship is a state that we somehow create by our own efforts.

He said, "Whatever we do in worship singing, the sacra- ments, listening to the preach- ing of the Word when we lift up who Christ is .and who we are sinners saved by grace - that's what produces thankful- ness and love for our neigh- bors, and that's true worship." ---new--"__ -, -- -"_-- -f- Copyrighted Material . ... vSyndicated Content: -m. ,:Available from Commercial News Providers -b O -- -n 0.- - - - ~ GRACE T' Continued from Page 1C If you could choose any dog in the world, Charlie would !probably not be your first [choice. He might not even be .ybur last choice. You might'ye s id, "Put that dog out of its misery" But Joan doesn't think any 'dog is too far gone to love. For Ithe past four years she's cared 'for a Down syndrome dog with ino skull that was only expected 'to live for a few weeks when :she got him from the vet The ;dog looks odd, but it wags its tail when it walks. Charlie does, too. After being t r adopted by Joan, after having its matted coat shaved bare, after being de-wormed and de- everythinged, after being loved and fed and loved some more, Charlie has turned into a brand new dog. He was recently certi- fied as a service dog, a dog with a purpose. I was thinking about Charlie and about another brand-new (human) friend while watching a video clip at church last week, a scene from "The Passion of the Christ" Carrying his cross to Golgotha, Jesus tells his mother that he is .mak- ing "all things new." Although the gospels don't record Jesus saying that before his death, he does say it after his Resurrection. In am - lba-w Revelation 21:5, John the apos- tle sees Christ upon his throne saying, "Behold, I make all things new." Some people think the world is hopelessly winding down, that it's progressively getting worse, "going to hell in a hand basket," as some say. Some think Jesus will return to claim his own any minute now, so why bother trying to make things better? Why not sit back, hunker down and wait for Armageddon? Other folks, however, think that while we're waiting for Jesus to return, we should work to restore, refresh and renew. To rule and subdue and to advance God's kingdom on the earth. They believe that he A* is all about making things new now, as well as later. That's what I tend to think That in the middle of incredi- ble disaster and destruction and the terribleness of life,. lives are being changed and made new. Just like Joan taking a lost and near-hopeless dog, left homeless in a storm, adopting it and giving it a new name and a new purpose, so God is taking lost and near-hopeless lives and doing the same. No, God does greater things he gives those he rescues his own Spirit and begins to conform them into his own likeness. Last week was Easter, but the message of new life doesn't end with the turning of a calendar - modlww~ - - page. God came to a broken earth to seek and save the lost and restore them to new life. To give them a future and a hope. He still comes, he still makes all things new. You might even say he makes tails wag and hearts rejoice again.

Answer.I (Answers Monday) Yesterday's Jumbles: PUDGY ERUPT MALLET JESTER Answer: When they settled their disagreement over a new bed, they PUT IT TO "REST' Bridge PHILLIP ALDER Newspaper Enterprise Assn. William Hazlitt, an English essayist, wrote: "There is nothing more likely to drive a man mad than the being unable to get rid of the idea of the distinction between right and wrong, and an obstinate, constitutional preference of the true to the agreeable." One must find bridge agreeable; otherwise, why play? And knowing the difference between a right and wrong bid or play will add to its agreeability - if that is a word. However, today's deal, where South is in four spades, is built around the word "preference." Why is that? If you and your partner use neg- ative doubles (recommended), South's one-spade response guar- antees at least a five-card suit. (With only four spades, South would make a negative double.) North has an automatic raise to game. West leads the heart 10 in answer to his partner's overcall. East wins with the heart king, cashes the heart ace, and ... what? Clearly West started with a dou- bleton heart, so East wants his partner to trump the third heart and to return a diamond for the contract-killing ruff. ' But how will West know to lead West A 5 10 2 * 8753 .1. 8 75 3 North 04-02-05 A K 9 6 4 S76 4 AKJ ' SAK J East A 8 3 2 SAK J 9 8 2 - 2 Q 10 9 6 4 South A A Q J 10 7 SQ5 3 SQ 10 9 6 4 4- Dealer: North Vulnerable: East-West East l V All pass Opening lead: V 10 South West North 14 1 A Pass 4 4 . a diamond, not a club? Because East sends a suit-preference sig- nal. He continues with the heart jack, his highest remaining heart asking for a shift to the higher- ranking of the other two side suits. (If East had a club void, he would lead the heart eight at trick three.) Finally, for experts: To emplih- size diamonds, East should break the normal rule and win trick ore with the heart ace before cashi-og the heart king, again signaling fqr diamonds.

Marriage cheaters hurt relations Dear Annie: I recently separated from my husband of four years due to his accusatory and jeal- ous nature. We also experienced prob- lems with our children from previous marriages, and decided it would be best to separate and attend counseling. .* | However, we only attended one session. Now, "Jared" no "(. 4 - longer is willing to go. I recently found out that Jared has been e-mailing my best friend, flirting and solic- iting sex. She is married and declined his offer, but I'm sure he's still trying. He also has made several attempts with other women to have an affair. ANN Should I continue to hold MAIL on to the hope that our mar- riage is worth saving, or do I accept the fact that a divorce is inevitable? Jared always tells me that I ,am the only woman he thinks about, but given the recent developments, can I ever trust him? Is this a brief glimpse of his true nature? And is it true that peo- -ple who accuse others of cheating are generally cheaters themselves? - Displaced Wife in Kansas Dear Kansas: Cheaters often accuse 'others of the same deed, but not every accuser is cheating. IfJared is soliciting sex from other women and he refuses to attend counseling sessions with you, he is not interested in preserving your marriage. Without counseling, he will not change his behavior, and you will never, trust him. We're sorry to say that it's ; time to cut him loose. ' Dear Annie: I have a brother who is married to a woman nobody likes. Over the past several years, she has managed to convince him to stop attending family functions, so now, we barely see him. Phone calls are infrequent. They have a 7- year-old son I have never NE'S met. .BOX I don't expect you to fix this relationship, but I recall you printed something in your column last year about Reconciliation Day. If you print the information again, I promise to send it to my brother and hope for the best. - Left-Out Sister Dear Sister. Relationships cannot be improved when only one person is will- ing to do the work, but we hope printing this will help. We are carrying on the tradition that April 2 be set aside as Reconciliation Day, a time to make the first move toward mending broken rela- tionships. It also would be the day on which we all agree to accept the olive branch extended by a former friend or estranged family member, and do our very best to put our differences in the past and start over. Dear Annie: I read the letter from "Tapped Out in Virginia," who com- plained that her husband's friend, Ralph, never antes his share for drinks and snacks at their dart parties. It may be that Ralph has had more than his share of hard knocks in life, all the guys know it, and they value his friendship beyond what his share of the munchies and drinks would be. Perhaps Ralph makes his attendance worth- while in other ways. People shouldn't be judged by their financial worth. I'd guess Ralph is con- tinually down on his luck and the guys are happy to share a good time out of pure friendship. She should trust her husband to do the right thing by Ralph. - Been There in Wisconsin Dear Wisconsin: If Ralph is on hard times, no one should penalize himi because he' cannot contribute.

Eclipse Community Forums - RDF feed Eclipse Community Forums HelloWorldSWT tutorial <![CDATA[Yes, I'm new to Java and Eclipse (an incredible tool!). I walked through the tutorial to build HelloWorld! and it worked. Then I tried walking through the tutorial for HelloWorldSWT. When I had problems, I deleted the HelloWorldSWT project and started over, I let the tutorial "do it for me" as much as possible. But it still doesn't work. I've tried the Organize Imports and can see no change. Where would I look to see the changes from this command? Here's the code for the HelloWorldSWT.java: public class HelloWorldSWT { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub Display display = new Display(); Shell shell = new Shell(display); shell.setText("Hello world!"); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } } Here's the errors after I compile: Exception in thread "main" java.lang.Error: Unresolved compilation problems: Display cannot be resolved to a type Display cannot be resolved to a type Shell cannot be resolved to a type Shell cannot be resolved to a type at HelloWorldSWT.main(HelloWorldSWT.java:9) The tutorial says: You will get compile errors. Right click in the Java editor and select Source > Organize Imports, then save your changes. I've done this. Many times. I've tried the ctrl+shift+o and I still get the compile errors. Why does this not work? I really appreciate any help you can give me. Thank you! ]]> Jason Clark 2012-09-03T01:31:44-00:00 Re: HelloWorldSWT tutorial <![CDATA[the same thing happened to me this is how I fixed it. go back to the import SWT part of the tutorial and make sure you import org.eclipse.swt.{platform}.{os}.{arch} and not the org.eclipse.swt.like mine would be org.eclipse.swt.win32.win32.x86 then continue on with the rest of the tutorial. when you click Source > Organize Imports in the java editor these two lines of code should appear import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; at the top automatically and the compile errors should be resolved.From there just run your application. Hope this helps !!!! ]]> Glen Zanabe 2012-09-05T15:16:50-00:00 Re: HelloWorldSWT tutorial <![CDATA[I am running 64 bit operating system windows 7 but I had to add org.eclipse.swt.win32.32x86 to make my swt application work. If I had not then the 2 import lines at the top of my project would not display when organizing imports. Do you have an idea of why that is?]]> luis villegas 2012-12-15T01:53:42-00:00 Re: HelloWorldSWT tutorial <![CDATA[Glen just find a 32 bit version of eclipse. Doesn't matter if it is indigo or MAC version if you are using MAC. This is what I have also. The only missing code is import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; THe is the reason we are getting the error: instances of this class is responsible for managing the connection between SWT. ]]> Andrew Geriane 2013-02-21T04:39:29-00:00 Re: HelloWorldSWT tutorial <![CDATA[hi i cant seem to find org.eclipse.swt.{platform}.{os}.{arch} i can only find this org.eclipse.swt 3.0.8. pls help ]]> Aditya Iyer 2013-04-23T12:50:56-00:00 Re: HelloWorldSWT tutorial <![CDATA[I think I have been through this.

[gutsy] gtkspell segfaults when trying to set the language on gtk.TextView
Bug Description
Binary package hint: gramps
susan@susan:~$ gramps
***MEMORY-
Segmentation fault (core dumped)
susan@susan:~$
see bug 116870 glibc
By the way, my python was the newest version available on 15 June.
It's segfaulting in aspell like so:
(gdb) bt
#0 0xb67ed76d in delete_
#1 0xb6801260 in ?? () from /usr/lib/
#2 0x756d2e42 in ?? ()
#3 0xb6801d36 in ?? () from /usr/lib/
#4 0xb6801d30 in ?? () from /usr/lib/
#5 0x08854bcc in ?? ()
#6 0x00000000 in ?? ()
This is most likely to be the gtkspell problem. If you can reproduce the gramps crash, try running the code below in terminal, without gramps. It should not crash if there's no bug. If this crashes then it's a gtkspell bug.
$ python
>>> import gtk
>>> import gtkspell
>>> import locale
>>> lang = locale.
>>> if lang == None:
... print "lang is None"
... success = False
... else:
... gtkspell.
... success = True
...
>>> success
True
Sorry Alex, I'm getting that script failing in several way, lots of syntax trouble. Can you re-write it, test it on your system, and load it as an attachment? Thanks
Duncan,
It was meant to be typed in, it is only a few lines.
If you want to cut/paste, here it is:
1. First start python
2. Run the stuff below
import gtk
import gtkspell
import locale
lang = locale.
if lang == None: print "lang is None"
else: gtkspell.
Thanks Alex, how's this: bad news?

... and the script crashed python2.5 which kicked apport into life and gave us bug report 122477, anything useful there?
No.
It's not bad news for gramps. It clearly demonstrates the issue with "gtkspell" python module. Guessing from my past experience with this on Debian, it is not because of the python bindings but rather in gtkspell itself. However, I am not 100% sure, it's just a guess.
just a standard crash report -- I didn't run the script mentioned above.
I get the same Segmentation fault as Duncan.
If Alex is right, and this is a gtkspell bug, where do we report it? Once it is reported, someone can link this bug to the gtkspell bug.
I don't think there's an "if" here. The python script is pretty short, and the only thing that could have crashed it is "gtkspell" python module.
This can be either a problem with python bindings for gtkspell: package python-
Or this can be a gtkspell library problem: package libgtkspell0
The sensible thing would be to re-assign this bug report to python-
I think the problem might be with aspell.

Can you try this script instead of gramps? Just run
$ strace python test.py
with the attached test.py file. This script has nothing to do with gramps and should crash just the same. Just to show that this is not a gramps issue and should be dealt with by gtkspell folks.
Here's the output on mu machine, just updated. For some reason I couldn't get it written to file, so I've lost some of the start of the output.
Looks like same crash to me.
Can we please drop the gramps thing now and work with the script? This issue just happened to cause gramps to crash too, but this is not gramps problem. The script demonstrates it clearly :-)
We need someone from MOTU to take on either getting this fixed or re-packaging the current version unhooked from gtkspell. I don't think we should wait much longer if GRAMPS is to make it into Gutsy. Anyone able to take this on?
Opened a bug at the GtkSpell page on SourceForge: http://
The problem is how this function is called. The GtkTextView is instanciated temporarely and is destroyed after the construction of the GtkSpell object, which triggers a destruction of the relevant parts needed by set_language. I personally would consider the call method wrong, but well.
A solution is to bump the refcnt of the textview in the GtkExtra python module (found in gnome-python-
So an immediate fix would be to move the gtk.TextView() into a temporary variable instead. With that it works even with the version of python-gtkspell currently in the archives.
gtkspell is buggy in terms that no way of gathering the information "is a spell checker available for this language" is exposed, gnome-python-extras is buggy because it does not increase the refcounter of the textview and gramps was buggy because it tried to acquire the information in a bogus way.
To fix the problem for real libgtkspell should be using a weak reference to the GtkTextView object, so that when the GtkTextView is destroyed GtkSpell is notified and removes the reference.
gramps (2.2.8-1ubuntu2) gutsy; urgency=low
[ Philipp Kern ]
* Work around a bug in gnome-python-extras which caused a deallocation
of the TextView in the check if a spell checker is present.
(LP: #120569)
[ Scott Kitterman ]
* Corrected XSBC-Original-
* Moved debhelper from Build-Depends-Indep to Build-Depends to satisfy
lintian
* Bumped standards version to 3.7.2 without further change
-- Scott Kitterman <email address hidden> Tue, 25 Sep 2007 12:49:53 -0400
that's not a gnome-python-extras bug
So I've worked around the issue in Gramps, but the fundamental problem remains.
I'd appreciate it if someone who understands Gnome would figure out which is the correct upstream to point fingers at.
It's like I said in comment 25. libgtkspell should be fixed. It's rather simple to fix using g_object_weak_ref API, but I don't have time.
I am not an expert, but I do think this is a gnome-python-extras bug. A python object should live as long as there are any references held to it.
In this case the Spell object still holds a reference to the TextView object. So the Spell object should increase the reference counter on the TextView.
The "C" GtkSpell itself is not designed to live without a corresponding TextView. (gtkspell_detach even destroys the GtkSpell "C" object)
One could argue about the approach used in gtkspell but as of now most of the functions depend on the view. The change suggested by Gustavo Carneiro would make gtkspell more robust against such situations, but I think it's a bigger change.
In the test script above, if done correctly, the TextView would be destroyed automatically, when the GtkSpell object is destroyed. After the last line there is no reference hold to the GtkSpell object anymore and the GC would destroy them both.
Philipp Kern: I would be interested in your code that tried to fix the issue in gnome-python-
Is this bug related to bug #261596?
Why is this bug still stuck on 'Fix released' and not actually committed?
Thanks for the report Susan Cragin ,://
Sadly, I can only confirm that it is fixed in oneiric, since that is what I have now and I just checked.
But it appears to be fixed.
I did use gramps last year and had no trouble with it, so I assume it has been fixed for some time. I'd say safe to say fixed in Natty.
I should say, I know that gramps works.
If the fix worked by removing gtk-spell, then gtk-spell could still have problems, and I wouldn't know about them.
But I suspect it's fixed because I have other programs that use gtk-spell and have had no problems.
I also saw the following information in the terminal I started gramps from:
/usr/share/
gramps/ Spell.py: 53: GtkWarning: gtk_text_ view_get_ buffer: assertion `GTK_IS_TEXT_VIEW (text_view)' failed Spell(gtk.

As mentioned in the first post in this series, I am launching a series of intensive WP7 tutorials. To get started I thought it was important to revisit this earlier post and make sure all the code is up to date.
[ Note, the intent is not to suggest that writing for the phone is the same as writing for the PC; they are very different platforms (see, for example, my discussion of TransMedia) but only to demonstrate that many of the coding skills you have as a Silverlight programmer will carry over, making the learning curve a good bit flatter ]
On Thursday, August 14, John Papa will air an episode of Silverlight TV in which we examine the premise that Silverlight Programmers are instant WP7 programmers. To demonstrate this, I created two applications side by side: a traditional Silverlight (Web) application and a WP7 application using the same code. (This refresh article brings the code up to the Beta release).
I’ll go through this step by step here, so that you can see the details that go>
Our next step is to create a form page in each application. Create a new Silverlight Child Window in the web application and a new Windows Phone Portrait Page in the phone version, and name each Form 1.We want to add a grid to each. In the case of the child window in the web version, within LayoutRoot, replacing the row definitions already in place;. (Take care that the code goes inside the inner grid in the Phone application)
the code you just added, to provide the remaining prompts.
<TextBlock Text="Last Name" Grid. <TextBox x: <TextBlock Text="Address" Grid. <TextBox x: <TextBlock Text="City" Grid. <TextBox x: <TextBlock Text="State, Zip" Grid. <StackPanel Grid. <TextBox x: <TextBox x: </StackPanel> <TextBlock Text="Email" Grid. <TextBox x:
Visual Studio creates the child window with OK and Cancel buttons, please remove them.
The DataSource
To have data to bind to, we’ll create a Customer class and give it a static method that will provide ) { FirstName = firstName; LastName = lastName; Street = street; City = city; State = state; Zip = zip; phone, change Foreground from Navy to White.
Changing Pages
The event handler for the Web application will instantiate the child window and “show it." Here is the complete MainPage.cs file,
using System.Windows; namespace SL_YouMayAlreadyBe { public partial class MainPage { public MainPage() { InitializeComponent(); ChangePage.Click += ChangePageClick; } void ChangePageClick(object sender, RoutedEventArgs e) { var wind = new Form1(); wind.VerticalAlignment = VerticalAlignment.Top; wind.Margin = new Thickness(0, 50, 0, 0); wind.Show(); } } }
The event handler for switching to the child window in the WP7 application can either set the RootVisual (declared in App.xaml.cs) or it can invoke the static Navigate method of the NavigationService
using System; using System.Windows; namespace WP7YouMayAlreadyBe { public partial class MainPage { public MainPage() { InitializeComponent(); ChangePage.Click += ChangePageClick; } void ChangePageClick(object sender, RoutedEventArgs e) { throw new NotImplementedException(); } } }
or if you prefer, the body of ChangePageClick can be changed.
My relatives every time say that I am killing my
time here at net, but I know I am getting familiarity everyday by reading thes
good articles.
Nice Post!
Thx 4 the info

Introduction to HTML+TIME
This topic documents a feature of HTML+TIME 2.0, which is obsolete as of Windows Internet Explorer 9.
HTML+TIME (Timed Interactive Multimedia Extensions), first released in Microsoft Internet Explorer 5, create multimedia-rich, interactive presentations, easily and with little or no scripting.
HTML+TIME 2.0 is based on the HTML+SMIL language profile in the Synchronized Multimedia Integration Language (SMIL) 2.0 working draft. SMIL 2.0 is the W3C successor to SMIL 1.0. HTML+TIME 2.0 is the successor to HTML+TIME 1.0.
This article covers the following topics:
- Benefits
- HTML+TIME Behaviors and Elements
- HTML+TIME Timing Model
- Authoring HTML+TIME
- Exclusive, Sequential and Parallel Time Container Elements
- Compatibility
- HTML+TIME Implementation Notes
- HTML+TIME Newsgroup
- Related Topics
Benefits
The following section contains information about the benefits of using HTML+TIME.
Dynamic Content
You can use HTML+TIME to add dynamic, interactive content to your Web pages. For example, you can create slide-show-style Web presentations with synchronized text, images, audio, video, and streaming media. You can create these presentations so that they are timed, interactive, or a combination of both.
Ease of Use
To add timing to an HTML document, all you have to do is add some new attributes to existing HTML elements. Thus, you can leverage your existing HTML knowledge when you add timing to your page. The HTML+TIME attributes specify when an element appears on a page, how long it remains displayed, and how the surrounding HTML elements are affected. In addition to the attributes, some new XML-based elements have been created to simplify incorporating media into Web pages. For example, you can use the
excl element to specify when a sound file should start playing, when it should stop, and how many times it should repeat.
HTML elements can be grouped into hierarchical relationships to allow for easy manipulation of multiple HTML elements at once. Grouping is also used to specify whether HTML elements appear and disappear sequentially on the page, or use independent timing. Element grouping is specified either by using the t:PAR, t:SEQ, or t:EXCL elements in a document, or by setting the TIMECONTAINER attribute.
Scripting Support
With HTML+TIME, you can use persistent XML elements and attributes to add timing to your HTML page. This means you don't have to know how to program with scripting languages to make your pages more dynamic. However, for people who already know how to use scripting languages, HTML+TIME supports a complete object model that extends the existing DHTML Object Model. Thus, you can use HTML+TIME properties, methods, and events to add even more interactive features to your Web pages.
HTML+TIME Behaviors and Elements
HTML+TIME is implemented as a DHTML default behavior, one of the powerful new features introduced in Internet Explorer 5. For more information about behaviors, see the Related Topics section of this document.
You can use all the HTML+TIME attributes listed in the reference pages with any timed HTML element. For a list of HTML elements that can be timed, see the Applies To section of the time and time2 behavior reference pages.
Internet Explorer 5.5 Update
The HTML+TIME 2.0 Reference lists the features implemented by the time2 behavior and supported in Internet Explorer 5.5 and later.
The HTML+TIME 1.0 Reference lists the features implemented by the time behavior and supported in Internet Explorer 5 and later.
HTML+TIME Timing Model
Most traditional animation runtime systems use either rigid timelines or pure, event-based relationships to model time. The rigid timeline model makes it more difficult to create interactive content. In this environment, you must add "jumps" to another pseudo-timeline to introduce interactive elements. In event-based models, interaction is easier to define, but it is more difficult to create timeline behaviors, such as sequences and precise synchronization of media elements.
HTML+TIME unifies these two timing models, taking the best of each and simplifying the process of authoring timed, interactive content. In the HTML+TIME model, you can use timeline attributes to describe static, or determinate, timeline relationships. This makes it easy to place elements in time and to ensure synchronization among media elements. You can author interactive content using a simple variant on the timeline attributes, where the begin and/or end times are tied to an event. Therefore, the actual begin and/or end values are indeterminate when you author the document. In reality, these times are event-based, but they can be defined as though they had traditional timing. When the associated event occurs, such as a user clicking a button, the indeterminate timing relationship is defined by the time at which the event occurs. At this point, the element is added into the running timeline as though it had been defined from the beginning.
This unified model makes it easy to define an animation that has tightly synchronized media, and to add a number of interactive elements that start when the user does something. The interactive elements can have a duration and repeat count just like other timed elements, even though they begin in response to an event. You can apply a single set of tools for timing and synchronization to any element. This makes the model easier to learn and less complicated, without sacrificing any flexibility.
HTML+TIME defines a schedule, or timeline, for all the affected elements to follow. The document timeline starts as soon as the page loads and continues to progress as long as the browser renders the page. If timing is applied to media elements, such as audio or video files, you can specify that the timeline will be tightly synchronized with other elements or the entire document. By default, media files that are not ready to play when scheduled will slip along the timeline and begin playing as soon as they become available. You can pause and resume the document timeline using methods from the object model.
HTML elements behave differently when you add time attributes, depending on the HTML element type. Although other categories might exist for HTML elements, HTML+TIME primarily distinguishes between content and style elements. Content elements include all elements that describe content to be displayed on the page, including the media elements introduced with HTML+TIME (t:ANIMATION, t:AUDIO, t:IMG, t:MEDIA, and t:VIDEO. Commonly used content elements include p, div, span, and table-related elements. Adding HTML+TIME attributes to a content element causes the element to appear and disappear over time. Style elements describe the style to be applied to an element. Commonly used style elements include b, i, and em. Adding HTML+TIME attributes to a style element causes the style to be applied to and removed from the element over time. For more information about style elements, see the HTML+TIME Implementation Notes section of this document.
Authoring HTML+TIME
Use the following steps to add timing to an HTML element.
- Create an XML Namespace
- Reference the time2 Behavior
- Specify Beginning and Ending Times
- Include an Action
Create an XML Namespace
When using any of the HTML+TIME elements, such as the t:EXCL, t:SEQ or t:PAR elements, you must declare the XML namespace
t: in the html tag, as shown in the following line of code:
To use the namespace, preface HTML+TIME elements with
t:. This string identifies the HTML+TIME elements as qualified XML namespace extensions. To establish
t: as the namespace, import the time2 behavior into the namespace as shown in the following line of code:
Reference the time2 Behavior
You must associate the element with the time2 behavior, so that the element is affected by the document timeline. To accomplish this, you can add the inline STYLE attribute to the HTML element as follows:
However, you might find it easier to associate an element with the time2 behavior by creating a Cascading Style Sheets (CSS) class attribute, as shown in the following sample:
Specify Beginning and Ending Times
You must specify when the HTML element should appear and for how long. This is accomplished by including the BEGIN and END attributes on the element. You can use the DUR attribute instead of END to specify an ending time relative to the element's BEGIN time. However, there is no functional difference between END and DUR, so you can use either one. If you do not set a BEGIN, END, or DUR time, the default value causes an element to begin displaying when the page loads, and the element remains displayed indefinitely. Therefore, the element appears static, as though you have not set any timing on that element.
The following sample shows lines of text that appear every two seconds and remain displayed for five seconds.
<HTML> <HEAD> <STYLE> .time {behavior: url(#default#time2);} </STYLE> </HEAD> <BODY> <P>This text appears right away. More lines to follow...</P> <P CLASS="time" BEGIN="2" DUR="5" >This appears after 2 seconds.</P> <P CLASS="time" BEGIN="4" DUR="5">This appears after 4 seconds.</P> <P CLASS="time" BEGIN="6" DUR="5">This appears after 6 seconds.</P> <P>This is the last line.</P> </BODY> </HTML>
Code example:
Include an Action
Although including an action is optional, you might want to use the TIMEACTION attribute to specify the action that is taken while the element is active on the timeline. In the DHTML Object model, two properties are available on the style object for turning on and off the display of an element. HTML+TIME changes the value of these properties over time. With DHTML, you can set the visibility property to
hidden or
visible. This property reserves space in the layout of the rendered document, as though the element is always visible. Therefore, the document does not reflow its contents as elements are dynamically displayed or hidden.
The default behavior for using HTML+TIME on a content element is
TIMEACTION="visibility". In contrast, when the DHTML display attribute is set to
none it does not reserve space in the rendered document. Therefore, the document reflows every time the value of the display attribute changes. To reflow the document using HTML+TIME, set the TIMEACTION attribute to
display.
As an alternative to displaying and hiding an element, you can set the TIMEACTION attribute to
style to make an inline style active on an element. If you use this option, any style property included on the element using the STYLE attribute is applied only while the element is active on the timeline; otherwise, the inline style is ignored. As of Internet Explorer 5.5, you can also modify the style of an element by specifying one or more class names for the TIMEACTION attribute.
When using a time container, you can set the TIMEACTION attribute to
none so that it performs no action. When this attribute is set to
none, only the child elements of the time container are visually affected while the timeline is active. If an element supports a Boolean
on property, you can use a TIMEACTION value of
onOff to make the
on property
true while the timeline is active on the element, or
false otherwise.
The following sample shows lines of text that appear every two seconds and remain displayed for five seconds. This is similar to the previous sample, but in this case the document reflows, as necessary, because the TIMEACTION attribute is set to
display. The TIMEACTION attribute is set to
style on the heading.
<HTML> <HEAD> <STYLE> .time {behavior: url(#default#time2);} </STYLE> </HEAD> <BODY> <H1 CLASS="time" BEGIN="0" DUR="11" TIMEACTION="style" STYLE="Color:Red;">timeAction</H1> <P>This text appears right away. More lines to follow...</P> <P CLASS="time" BEGIN="2" DUR="5" TIMEACTION="display">This appears after 2 seconds.</P> <P CLASS="time" BEGIN="4" DUR="5" TIMEACTION="display">This appears after 4 seconds.</P> <P CLASS="time" BEGIN="6" DUR="5" TIMEACTION="display">This appears after 6 seconds.</P> <P>This is the last line.</P> </BODY> </HTML>
Code example:
Exclusive, Sequential and Parallel Time Container Elements
You can use HTML+TIME to specify timing for individual elements displayed on the page. You can also use it to create a timeline that groups elements together and specifies their timing relative to each element's predecessor in the timeline. The following example uses the TIMECONTAINER attribute set to
excl to create a time container that allows only one element to play at a time.
<HTML> <HEAD> <STYLE> .time {behavior: url(#default#time2);} </STYLE> </HEAD> <BODY> <DIV CLASS="time" TIMECONTAINER="excl"> <DIV CLASS="time" BEGIN="0" DUR="2" TIMEACTION="display">First line of text.</DIV> <DIV CLASS="time" BEGIN="2" DUR="2" TIMEACTION="display">Second line of text.</DIV> <DIV CLASS="time" BEGIN="4" DUR="2" TIMEACTION="display">Third line of text.</DIV> <DIV CLASS="time" BEGIN="6" TIMEACTION="display">Fourth line of text.</DIV> </DIV> </BODY> </HTML>
Code example:
You can easily create slide-show-style presentations using timing sequences to display a series of images, one after the other, along with synchronized text. The following example uses the TIMECONTAINER attribute to create a sequential time container.
<HTML> <HEAD> <STYLE> .time {behavior: url(#default#time2);} </STYLE> </HEAD> <BODY> <DIV CLASS="time" TIMECONTAINER="seq"> <DIV CLASS="time" DUR="2" TIMEACTION="display">First line of text.</DIV> <DIV CLASS="time" DUR="2" TIMEACTION="display">Second line of text.</DIV> <DIV CLASS="time" DUR="2" TIMEACTION="display">Third line of text.</DIV> <DIV CLASS="time" TIMEACTION="display">Fourth line of text.</DIV> </DIV> </BODY> </HTML>
Code example:
You must declare the duration of each element in the sequence. Since the duration is omitted on the last element, it remains displayed indefinitely. Grouping the elements in a sequence makes it easy to manipulate the entire group of elements at once, rather than individually. For example, you can add the BEGIN attribute to the sequence time container to make the entire sequence wait before it begins playing.
If you want to group elements without displaying them in a sequence, you can create a parallel timeline by setting the TIMECONTAINER attribute to
par on the time container element. In contrast to a sequence, you can use parallel timelines to display and hide elements without any implicit dependencies on other elements. This allows more than one element to be active on the timeline, and you can have as few or as many elements active on the timeline as you want—there is no minimum or maximum requirement. The following sample shows how a parallel timeline is used for repeating a group of elements with overlapping timelines.
<HTML> <HEAD> <STYLE> .time {behavior: url(#default#time2);} </STYLE> </HEAD> <BODY> <DIV CLASS="time" REPEATCOUNT="5" DUR="10" TIMECONTAINER="par"> <DIV CLASS="time" BEGIN="0" DUR="4">First line of text.</DIV> <DIV CLASS="time" BEGIN="2" DUR="4">Second line of text.</DIV> <DIV CLASS="time" BEGIN="4" DUR="4">Third line of text.</DIV> <DIV CLASS="time" BEGIN="6" DUR="4">Fourth line of text.</DIV> </DIV> </BODY> </HTML>
Code example:
Instead of using the TIMECONTAINER attribute to group HTML elements on a timeline, you can use the t:PAR or t:SEQ elements. For example, in the previous sample that shows a sequence, you could have used the t:SEQ element instead of the div to yield the same results.
The following example declares the XML namespace
t: in the html tag and imports the time2 behavior into that namespace because it uses the t:SEQ custom element.
<HTML XMLNS: <HEAD> <STYLE> .time {behavior: url(#default#time2);} </STYLE> <?IMPORT namespace="t" implementation="#default#time2"> </HEAD> <BODY> <t:SEQ> <DIV CLASS="time" DUR="2">First line of text.</DIV> <DIV CLASS="time" DUR="2">Second line of text.</DIV> <DIV CLASS="time" DUR="2">Third line of text.</DIV> <DIV CLASS="time">Fourth line of text.</DIV> </t:SEQ> </BODY> </HTML>
Code example:
Compatibility
HTML+TIME features are available as of Internet Explorer 5 and are not supported in earlier browser versions. If an earlier version of Internet Explorer or a non-Internet Explorer browser encounters a reference to a behavior, the style is ignored, and the element is rendered as normal on the page. However, scripting errors might occur in cases where the behavior being used exposes properties, methods, or events. To address these errors, you need to use some version-checking script.
Internet Explorer 5.5 Update
All of the features of the time behavior are still available in Internet Explorer 5.5. However, we strongly recommend that you begin using the time2 behavior, which implements the HTML+SMIL language profile as defined in the working draft of the SMIL 2.0 specification.
HTML+TIME Implementation Notes
The following list contains information about the initial version of HTML+TIME in Internet Explorer 5, including differences between this implementation and the W3C submission.
- Style elements, such as b, i, and em, are not fully supported in the initial version of HTML+TIME. Instead, style elements are controlled in the same way as content elements: by displaying and hiding their contents. However, you can set the timing on inline styles associated with an element. For information about how to apply timing to an element's inline style, see the TIMEACTION attribute.
- When adding timing to an image, use the new HTML+TIME t:IMG element instead of the HTML img element.
HTML+TIME Newsgroup
The HTML+TIME newsgroup is a forum for users to share ideas, ask questions, and relay comments about HTML+TIME. The newsgroup is intended for user-to-user support; however, Microsoft does monitor it for product-feedback purposes. To access the newsgroup, use the following information with your favorite newsgroup reader.

I always had interest in security issues, specially about application use security. I believe user authentication and authorization is one of the main thoughts in application development (even if not the first to be coded).
Despite all my interest, just recently, I got the time to study the resources and advantages .NET offers to this matter. And there are many things I found.
Since MS launched Windows 2000 family, there is the Active Directory (AD). Whoever has studied it is aware this is based on a less used Internet protocol called LDAP. Its job is, basically, manage users, groups and other security stuff on a domain in a simple way. The greater advantage is interoperability, since one can replace AD for another LDAP server given some work.
For developers, .NET comes with a full namespace to ease working with both AD and LDAP, System.DirectoryServices, which includes LDAP v3. On the following samples, I will use a fake domain called AD1.
System.DirectoryServices
private static string domain = "AD1";
public static bool LogonValid(string userName, string password) {
DirectoryEntry de = new DirectoryEntry(null, domain +
"\\" + userName, password);
try {
object o = de.NativeObject;
DirectorySearcher ds = new DirectorySearcher(de);
ds.Filter = "samaccountname=" + userName;
ds.PropertiesToLoad.Add("cn");
SearchResult sr = ds.FindOne();
if(sr == null) throw new Exception();
return true;
} catch {
return false;
}
}
public static bool IsInRole(string userName, string role) {
try {
role = role.ToLowerInvariant();
DirectorySearcher ds = new DirectorySearcher(new DirectoryEntry(null));
ds.Filter = "samaccountname=" + userName;
SearchResult sr = ds.FindOne();
DirectoryEntry de = sr.GetDirectoryEntry();
PropertyValueCollection dir = de.Properties["memberOf"];
for(int i = 0; i < dir.Count; ++i) {
string s = dir[i].ToString().Substring(3);
s = s.Substring(0, s.IndexOf(',')).ToLowerInvariant();
if(s == role) return true;
}
throw new Exception();
} catch {
return false;
}
}
These methods are implemented to work with a single application. The sources provided with this article are full implementations of IIdentity and IPrincipal interfaces. They are more suitable for developing ASP.NET Forms Authentication based on AD.
IIdentity
IPrincipal
Applications can benefit more efficiently and easily from Active Directory by using another set of classes, also avoiding to create their own logon process. Developers should keep in mind this is a Windows-dependent solution.
But how is that possible? This time, we'll use Windows logon itself to authenticate the user, using only two classes in the System.Security.Principals namespace. Yet, this can be done in two ways:
System.Security.Principals
IIdentity wi = WindowsIdentity.GetCurrent();
IPrincipal wp = new WindowsPrincipal((WindowsIdentity)wi);
// ...or...
IPrincipal wp = Thread.CurrentPrincipal;
IIdentity wi = wp.Identity;
From now on, we can check if a user belongs to a user group by simply calling the method IsInRole defined by the IPrincipal interface. It's important to remember that domain groups must specify the domain (e.g. "AD1\Administrators"), or the group evaluated will belong to the machine running the code.
IsInRole
A call to IsInRole is an alternate when the group name is known only at runtime. Once it is known during design time, methods and even full classes can be blocked using PrincipalPermissionAttribute. This can allow access to specific groups (roles), users, or simply user is authenticated (remember, in Windows 9x/ME, the user can cancel logon).
PrincipalPermissionAttribute
[PrincipalPermission(SecurityAction.Demand, Role="AD1\\Administrators")]
[PrincipalPermission(SecurityAction.Demand, User="AD1\\harkos")]
[PrincipalPermission(SecurityAction.Demand, Authenticated=true)]
The Windows identity can also be used to authenticate users on intranet sites. This configuration requires no code at all but adjusting the web.config file to the following lines:
<authentication mode="Windows"/>
<authorization>
<allow roles="AD1\Administrators"/>
</authorization>
<identity impersonate="true"/>
The last line is not mandatory, but it makes the ASP.NET process to impersonate the user accessing the site, thus making the site more secure and allowing the use of PrincipalPermissionAttributes through your ASP.NET code.
PrincipalPermissionAttributes
User authentication and authorization using Windows/Active Directory is the best way to protect applications running inside a corporation, like a webmail or ERP application, easing management and task delegation and avoiding multiple passwords. Of course, nothing here applies if users should or must not be associated with domain user accounts, like a blog or an event registration. In these cases, a larger implementation with or without databases is more suitable.

Quick Search API Sample
By Geertjan-Oracle on Jul 18, 2008.
Dear Geertjan, how to use quick search panel in a custom form. For example I have a list of clients, and a JPanel (on TopComponent) with a TextField named "Client". I want to equip this field or replace it with a field like in quick search.
Posted by Alexander on June 03, 2010 at 05:46 PM PDT #
Hello Geertjan. I'm having some problems with my implementation of this API. I got the searchprovider set up correctly and the application searches beutifully amongst my customers and articles.
But.
When the search has found a article, for example, I have a action that opens that article in my articleeditor. When i open the article, the quicksearch textfield says, "( no results )", in evil red text.
Do you have any idea of why this is?
Posted by Ingemar Skelander on April 05, 2013 at 05:51 AM PDT #
Got the same "no results" error issue though the search found a few results. Any insight will be much appreciated. Cheers.
Posted by guest on April 13, 2013 at 07:41 AM PDT #
You're saying that you followed this tutorial?
Posted by Geertjan on April 13, 2013 at 08:30 AM PDT #
Tried it in NetBeans Platform 7.3. Works perfectly. So if you're not going to provide code showing the problem, I'm not going to be able to help.
Posted by Geertjan on April 13, 2013 at 08:46 AM PDT #
Hello again Geertjan. I will provide some sample code of the SearchProvider.
public class ArticleSearchProvider implements SearchProvider {
@Override
public void evaluate(SearchRequest request, SearchResponse response)
{
List<Article> allArticles = findAllArticles() // not the real call
List<Article> viableResults = new ArrayList<Article>();
for (Article article : articles) {
if (isCompatibleId(article, request)) {
viableResults.add(article);
} else if (isCompatibleName(article, request)) {
viableResults.add(article);
} else if (isCompatiblePrice(article, request)) {
viableResults.add(article);
}
}
for (Article article : viableResults) {
ArticleAction articleAction
= new ArticleAction(viableResults, article);
if(!response.addResult(articleAction, article.getName() + " " +
article.getNumber())) {
return;
}
}
}
}
and the Runnable, ArticleAction, just posts the selected article to the global lookup where it is processed and the articleeditor opens with the selected article.
Sorry that the formatting of the code is kinda messed up.
Posted by Ingemar Skelander on April 15, 2013 at 06:35 AM PDT #
Just answer the question, please. Did you follow the tutorial? Ignoring your comments until you answer the question. Also, just join the dev mailing list and ask your questions there.
Posted by Geertjan on April 15, 2013 at 06:48 AM PDT #
Sorry, I forgot to answer the tutorial question. Yes I followed the tutorial. I will join the mailing list, so no point in continuing here.
Thanks.

NAME
posix_openpt -- open a pseudo-terminal device
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h> #include <fcntl.h> int posix_openpt(int oflag);
DESCRIPTION
The posix_openpt() function allocates a new pseudo-terminal and establishes a connection with its master device. A slave device shall be created in /dev/pts. After the pseudo-terminal has been allocated, the slave device should have the proper permissions before it can be used (see grantpt(3)). The name of the slave device can be determined by calling ptsname(3). posix_openpt() function shall fail when oflag contains other values.
RETURN VALUES
Upon successful completion, the posix_openpt() function shall allocate a new pseudo-terminal device and return a non-negative integer representing a file descriptor, which is connected to its master device. Otherwise, -1 shall be returned and errno set to indicate the error.
ERRORS
The posix_openpt() function shall fail if: [ENFILE] The system file table is full. [EINVAL] The value of oflag is not valid. [EAGAIN] Out of pseudo-terminal resources.
SEE ALSO
pts(4), ptsname(3), tty(4)
STANDARDS
The posix_openpt() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
The posix_openpt() function appeared in FreeBSD 5.0. In FreeBSD 8.0, this function was changed to a system call.
NOTES
The flag O_NOCTTY is included for compatibility; in FreeBSD, opening a terminal does not cause it to become a process's controlling terminal.

<rdar://problem/6150322> In Gmail, a crash occurs at KJS::Machine::privateExecute() when applying list styling to text after a quote had been removed
<>
Reviewed by Cameron Zwarich.
This crash was caused by "depth()" incorrectly determining the scope depth
of a 0 depth function without a full scope chain. Because such a function
would not have an activation the depth function would return the scope depth
of the parent frame, thus triggering an incorrect unwind. Any subsequent
look up that walked the scope chain would result in incorrect behaviour,
leading to a crash or incorrect variable resolution. This can only actually
happen in try...finally statements as that's the only path that can result in
the need to unwind the scope chain, but not force the function to need a
full scope chain.

I changed JSCallbackObjectData, Arguments, JSArray, and RegExpObject to

I changed InternalFunction to store the function's name in the property
map.
I changed JSGlobalObjectData to use a virtual destructor, so WebCore's
JSDOMWindowBaseData could inherit from it safely. (It's a strange design
for JSDOMWindowBase to allocate an object that JSGlobalObject deletes,
but that's really our only option, given the size constraint.)
I also added a bunch of compile-time ASSERTs, and removed lots of comments
in JSObject.h because they were often out of date, and they got in the
way of reading what was actually going on.
Also renamed JSArray::getLength to JSArray::length, to match our style
guidelines.

Sped up property access for array.length and string.length by adding a
mechanism for returning a temporary value directly instead of returning
a pointer to a function that retrieves the value.
Also removed some unused cruft from PropertySlot.
SunSpider says 0.5% - 1.2% faster.
NOTE: This optimization is not a good idea in general, because it's
actually a pessimization in the case of resolve for assignment,
and it may get in the way of other optimizations in the future.

Don't start preloading body resources before the head is complete. This prevents

Works by queuing up found body preloads to DocLoader and only issuing them

With bandwidth capped to 300kbit/s this speeds up cnn.com initial display by ~25% or 5s

Some loader performance tweaks:
- Make stylesheets highest priority instead of scripts. We block script execution on stylesheets. Especially if a stylesheet @imports other stylesheets it is important to get them to the front of the queue to not delay rendering.
- Issue the first resource load for a host immediately even if the resource is low priority. TCP connection setup can take long time when latency is high so it is good to get started early.
- When the document is fully parsed and stylesheets have been loaded there is no need to keep managing the load queues. Issue remaining loads to the network layer.

Allow JSImmediate to hold 31 bit signed integer immediate values. The low two bits of a
JSValue* are a tag, with the tag value 00 indicating the JSValue* is a pointer to a
JSCell. Non-zero tag values used to indicate that the JSValue* is not a real pointer,
but instead holds an immediate value encoded within the pointer. This patch changes the
encoding so both the tag values 01 and 11 indicate the value is a signed integer, allowing

Is C Still A Suitable Language Today?
Damien Katz, Couchbase, believes that C is still a great language for back-end programming, while other developers argue that C has too many flaws, supporting C++ or Java, while others like neither.
In a recent blog post entitled The Unreasonable Effectiveness of C, Damien Katz, the Creator of CouchDB, affirms that C is a great language for the back-end, supporting it in spite of more modern languages such as C++ , Java, or even Erlang or Ruby. Katz does not think C is simply better than any other language out there, but when “raw performance and reliability are critical, C is very, very hard to beat,” - quote taken from a subsequent post meant to clarify his position.
While initially doing much of CouchDB in Erlang, Katz became unhappy with it after spending .
For that and for performance reasons, Katz decided to progressively rewrite “more of the Couchbase code in C, and choosing it as the first option for more new features.” Interestingly, C has proven to be “much more predictable when we'll hit issues and how to debug and fix them. In the long run, it's more productive.”
Katz outlines several reasons making C better than higher level languages such as C++ or Java for the back-end:
- Expressiveness – “The syntax and semantics of C is amazingly powerful and expressive. It makes it easy to reason about high level algorithms and low level hardware at the same time. Its semantics are so simple and the syntax so powerful it lowers the cognitive load substantially, letting the programmer focus on what's important.”
- Simplicity – “C is a weak, statically typed language and its type system is quite simple. … What sounds like a weakness ends up being a virtue: the "surface area" of C APIs tend to be simple and small. Instead of massive frameworks, there is a strong tendency and culture to create small libraries that are lightweight abstractions over simple types.”
- Speed and Memory Footprint – .”
- Faster Development Cycle – “Critically important to developer efficiency and productivity is the "build, run, debug" cycle. The faster the cycle is, the more interactive development is, and the more you stay in the state of flow and on task. C has the fastest development interactivity of any mainstream statically typed language.”
- Debugging – .”
- Cross-platform – .”
Katz also agrees C has “many flaws”:
…!
Katz’s love affair with C seems to originate from the need to push Couchbase’s performance limits and debugging problems arising from combining C plugins with the Erlang VM. He does not consider C++, Go or D as a better replacement for C, but he thinks Rust could be “the language of my dreams” if it achieves “C-like performance but safe with Erlang concurrency and robustness built in.”
Katz’ post has sparked a wide debate on Reddit and Hacker News, many developers arguing the virtues of C and suggesting other languages instead. robinei blames string manipulation and error checking hassles:
I always want to get back to C (from C++ among others), and when I do it's usually refreshingly simple in some ways. It feels good!
But then I need to do string manipulation, or some such awkward activity..
Where lots of allocations happen, it is a pain to have to match every single one with an explicit free. I try to fix this by creating fancy trees of arena allocators, and Go-like slice-strings, but in the end C's lack of useful syntactic tools (above namespace-prefixed functions) make everything seem much more awkward than it could be. (and allocating everything into arenas is also quite painful)
I see source files become twice as long as they need to because of explicit error checking (doesn't normally happen, but in some libraries like sqlite, anything can fail).
There are just so many things that drain my energy, and make me dissatisfied.
After a little bit of all that, I crawl back to where I came from. Usually C++.
madhadron proposes a “more realistic view of C”:
- C is straightforward to compile into fast machine code...on a PDP-11. …
- C's standard library is a joke. Its shortcomings, particularly around string handling, have been responsible for an appalling fraction of the security holes of the past forty years.
- C's tooling is hardly something to brag about, especially compared to its contemporaries like Smalltalk and Lisp. Most of the debuggers people use with C are command line monstrosities. Compare them to the standard debuggers of, say, Squeak or Allegro Common Lisp.
- Claiming a fast build/debug/run cycle for C is sad. It seems fast because of the failure in this area of C++. Go look at Turbo Pascal if you want to know how to make the build/debug/run cycle fast.
- Claiming that C is callable from anywhere via its standard ABI equates all the world with Unix. Sadly, that's almost true today, though, but maybe it's because of the ubiquity of C rather than the other way around.
geophile is dissatisfied with all of them:
C/C++/Java. A programmer's version of Rock/Paper/Scissors.
I started out in C, many years ago. I found myself using macros and libraries to provide useful combinations of state and functions. I was reinventing objects and found C++.
I was a very happy user of C++ for many years, starting very early on (cfront days). But I was burned by the complexity of the language, and the extremely subtle interaction of features. And I was tired of memory management. I was longing for Java, and then it appeared.
And I was happy. As I was learning the language, I was sure I missed something. Every object is in the heap? Really? There is really no way to have one object physically embedded within another? But everything else was so nice, I didn't care.
And now I'm writing a couple of system that would like to use many gigabytes of memory, containing millions of objects, some small, some large. The per-object overhead is killing me. GC tuning is a nightmare. I'm implementing suballocation schemes. I'm writing micro-benchmarks to compare working with ordinary objects with objects serialized to byte arrays. And since C++ has become a hideous mess, far more complicated than the early version that burned me, I long for C again.
So I don't like any language right now.
For some, C looks too flawed and unproductive to be useful today, but others still manage to make good use of it in spite of its peculiarities. The developer community would be probable better off avoiding a war over the best language out there, and rather trying to understand the tradeoffs of each language, choosing the best suited considering the project at hand and the skills available. After all, no language is perfect.
Depends on your goals and environment...

Mark Peskin
Overall, if you're doing a large, complex, and sustained project with a significant developer staff, I think you're much better off with Java (or Scala, etc.). Save the C for the odd (and increasingly less frequent) occasions where you really need native code, and use a message-based system to integrate the two (JNI sucks). Forget about C++.

I'm with Mark and - to some extent - Damien on this one..

mbeddr was designed to better support embedded software development (although not limited to that) for small as well as large systems based on an extensible version of C language and IDE. Existing extensions include interfaces with pre- and postconditions, components, state machines and physical units, as well as support for requirements tracing and product line variability. Based on these abstractions, mbeddr also supports formal verification based on model checking and SMT solving.
With that approach C can be made "scalable" for larger projects and teams. In addition it allows the introduction modern programming principles. By extending mbeddr you even add primitives for e.g. messaging.
Of course you cannot blame C for race conditions...
by
Patrick Viry
So instead of blaming the Erlang runtime for race conditions, you'll end up blaming the C threading library you selected. This is hardly an argument against using Erlang.
On the contrary, the threading model provided by the various C libraries is so complex - compared to the Erlang concurrency model - that you'd probably spend months debugging race conditions in your own | http://www.infoq.com/news/2013/01/C-Language | CC-MAIN-2015-18 | en | refinedweb |
Creating Documents by Using the Open XML Format SDK 2.0 CTP (Part 3 of 3)
Summary: See how to accomplish common scenarios by using the Open XML Format SDK APIs. Create Microsoft Office PowerPoint 2007 presentations from data in a database, assemble Microsoft Office Word 2007 documents from smaller documents, and bind content controls to custom XML, all by using the Open XML Format SDK 2.0 (CTP) APIs (12 printed pages)
Zeyad Rajabi, Microsoft Corporation
Frank Rice, Microsoft Corporation
February 2009
Applies to: Microsoft Office Excel 2007, Microsoft Office Word 2007, Microsoft Office Word 2007
Contents CTP (Part 2 of 3) and Creating Documents by Using the Open XML Format SDK 2.0 (Part 3 of 3) present common scenario and show you lots of sample code.
You can access the Open XML Format SDK 2.0 (CTP) from the following locations:
Download sample: Sample Code downloads for the Open XML Format SDK 2.0 (CTP).
Creating a Presentation Report Based on Data
The Open XML Format SDK provides a set of Microsoft .NET Framework application programming interfaces (APIs) that allows you to create and manipulate documents in the Open XML Formats in both client and server environments without requiring the Microsoft Office client applications.
The following solutions use the Open XML Format SDK 2.0 (CTP).
In the following section, you go through the steps to create a rich Microsoft Office PowerPoint 2007 presentation report from data in a database.
Scenario: Document Assembly
Imagine a scenario where you are a developer working for a fictional company called Adventure Works. In this company, a database is used to store all data pertaining to its sales force. The company needs to track the contact information, territories they own, total sales, and bonuses for the sales team. You will build a report generation tool that can take this data and create a Microsoft Office PowerPoint 2007 presentation. The sales team wants this solution to run on the server, so the PowerPoint client application cannot be used.
Solution
Before discussing the details of the solution, there are two prerequisites:
The solution is based on the Adventure Works database built for Microsoft SQL Server 2005. The Adventure Works database can be downloaded at Adventure Works database
The solution requires that you update the Adventure Works database to include contact photos.
Download sample: Sample Code downloads for the Open XML Format SDK 2.0 (CTP).
Step 1 – Create a Template
In this scenario you read sales personal data and create a PowerPoint presentation report. First, you need to create a presentation template for the solution. In this instance, the presentation template should contain a slide with placeholder regions for the following information:
Sales person contact information, such as name, e-mail address and photo
Sales summary information, such as territory owned by sales person, total sales made by sales person, sales quota
Extra information, such as bonus amount and commission percentage
The slide template looks like the following figure.
Step 2 – Clone the Slide Template
For each sales person in Adventure Works, clone the slide template, shown in figure 1, and fill in the necessary information with data from the database. The code:
Creates a slide for each sales person
Copies the content from the slide template to a new slide
Ensures that the new slide references the slide template's slide layout
Adds the new slide to the end of the presentation (similar to adding a node to the end of a linked list)
SlidePart CloneSlidePart(PresentationPart presentationPart, SlidePart slideTemplate) { //Create a new slide part in the presentation. SlidePart newSlidePart = presentationPart.AddNewPart<SlidePart>("newSlide" + i); i++; //Add the slide template content into the new slide. newSlidePart.FeedData(slideTemplate.GetStream(FileMode.Open)); //Make sure the new slide references the proper slide layout. newSlidePart.AddPart(slideTemplate.SlideLayoutPart); /); return newSlidePart; }
Step 3 – Swap the Placeholder Text
At this point, you cloned the slide template and added it to the presentation. Next, replace the placeholder text in the new slide with the appropriate data. The following method locates all placeholder locations and replaces the placeholder text with strings from a given slide part.
void SwapPlaceholderText(SlidePart slidePart, string placeholder, string value) { //Find and get all the placeholder text locations. List<Drawing.Text> textList = slidePart.Slide.Descendants<Drawing.Text>().Where(t => t.Text.Equals(placeholder)).ToList(); //Swap the placeholder text with the text from DB foreach (Drawing.Text text in textList) text.Text = value; }
Step 4 – Swap out Placeholder Photo
The slide template includes one placeholder picture that is intended to represent the image of a sales person. To replace this photo, the code:
Adds an image part to the new slide based on the slide template
Inserts the image data into the newly-added image part
Places the photo reference from the placeholder image into the new image
Replacing the photo is simple because images are referenced to by using Ids. In this instance, find the image reference and replace it with the image reference of the new image. The following code accomplishes this.
Step 5 – Delete Template Slide
To complete this solution, delete the slide template. As you know the relationship Id of the slide template, the following code deletes the slide.
void DeleteTemplateSlide(PresentationPart presentationPart, SlidePart slideTemplate) { //Get the list of slide ids. SlideIdList slideIdList = presentationPart.Presentation.SlideIdList; //Delete the template slide reference. foreach (SlideId slideId in slideIdList.ChildElements) { if (slideId.RelationshipId.Value.Equals("rId3")) slideIdList.RemoveChild(slideId); } //Delete the template slide. presentationPart.DeletePart(slideTemplate); }
The Result
Running the code produces the output in the following figure.
Merging Multiple Word Documents
A common request for word-processing documents is to merge multiple documents into a single document. In this section, you use altChunks and the Open XML Format SDK 2.0 to create a robust document assembly solution.
Scenario: Document Assembly
In this scenario, you are a developer for a book publisher company that specializes in education based books. This company typically has one or more authors write chapters for a given book. Each of these chapters is written as a separate document. In this scenario, the company commissioned a book on the solar system where the book is divided into a separate chapter each element of the solar system such as the planets and the sun. You need to write a solution to merge all these documents into a single document.
Solution
Before describing the details of this solution, there are a couple of different approaches to solve this problem:
Use altChunks to merge the documents. For more information about altChunks, see Leveraging Content in Other Formats.
Manually merge documents together by using copy and paste
Using altChunks is the easier of the two choices. Not only can you use altChunks for WordprocessingML documents, you can also use them with HTML, XML, RTF, and plain text.
Manually merging multiple documents is feasible but requires you to handle a number of issues. For example, you need to deal with conflicts related to different styles, bullets, numbering, comments, headers, and footers.
Step 1 – Create a Template
The first step is to create a template for the book. In the template, you merge chapters into specific locations within the template by using content controls. Content controls allow you to uniquely identify a specific region within a document. For more information about content controls, see Meet the Controls.
Each content control you add to the template has the name of the chapter for that location. For example, as shown in the following figure, there is a content control named Earth.
Step 2 – Find Specific Content Controls
The template is complete so you programmatically locate content controls based on the chapter titles. This task is easy with the Open XML Format SDK 2.0. The following code opens the document and finds all content controls represented as SdtBlock with an alias set to the source file to merge.
MergeSourceDocument(string sourceFile, string destinationFile) {<Alias>().Val.Value)).ToList(); ... } }
Step 3 – Add altChunk and Replace the Content Control
In this step, you replace the content controls with the document text by using altChunks. You can merge the documents with altChunks by doing the following tasks:
Adding the altChunk part to the document package
Importing data from the subdocument into the altChunk part
Adding a reference to altChunk into the main document part
The following code accomplishes these tasks. the content control with altChunk information. foreach (SdtBlock sdt in sdtList) { OpenXmlElement parent = sdt.Parent; parent.InsertAfter(altChunk, sdt); sdt.Remove(); } ... }
The Result
Running the code produces the solar-system book divided into a chapter for each components of the solar-system. To summarize, using altChunks automatically ensures the following:
The final document has consistent styles applied.
Images, comments, and tracked changes are all included as part of the merged document.
Bullets and numbering work as expected.
The following figure shows the final document.
Binding Content Controls to Custom XML
In the previous section, you used content controls to provide semantic structure within a document. In this section, you use content controls to bind to custom XML.
Scenario: Generate Sales Contracts on the Server
In this scenario, you are a developer for a law firm that specializes in writing legal contracts to sell various properties. The company uses the same template for all property contracts. The only difference in the contracts is the data used. For example, the contract displays who is selling the property and the address of the property. You need to write a solution that allows lawyers to automatically insert the data into the template. Additional, the solution should generate the document on the server.
Solution
This solution is based on concepts described in a post from the Word team blog: Separate Yet Equal. This solution uses content controls to bind to custom XML. By using bound content controls, you are separating the presentation of the documentation from the data stored in a separate custom XML part. Binding content controls gives the following functionality:
When a user types into a bound content control, the data in the custom XML is also updated.
When the data in the custom XML part is updated, the content in the bound content control is also updated.
To accomplish the server requirement, the solution is built with Microsoft ASP.NET. The solution’s Web site contains several form fields representing the data to insert into the document. To insert the data into the document, you generate a custom XML file based on this data and insert the file into the WordprocessingML package.
Download sample: Sample Code downloads for the Open XML Format SDK 2.0 (CTP).
Step 1 – Create a Template
The first step is to set up the template. In this instance, the template is a sales contract with content controls located where data is to be inserted. The template looks like the following figure.
These content controls delineate semantic regions and bind to the custom XML. This binding is accomplished by using the namespace of the custom XML file and using a XPath expression to identify the element to bind to. The following is an example of XML markup that specifies this binding.
There are three ways to bind to content controls:
By using Content Control Tool Kit. This Word add-in makes binding content controls to XML easy and intuitive.
By using the Word object model. You can use ContentControl.XMLMapping.SetMapping() method.
By directly manipulating the underlying XML. You can use the Open XML Format SDK 2.0 for this.
In this template, you bind the content controls to an empty custom XML file. This custom XML file contains no data. Binding to an empty custom XML file ensures that just the placeholder text of the content controls is shown.
Step 2 – Create the ASP.NET Front-End Web site
The next step is to create a front-end Web site that allows users to insert data into the document. For this step, you create a simple Microsoft ASP.NET site that looks similar to the following figure.
In the back end of the Web site, a custom XML file containing the data is inserted into the Wordprocessing document.
Step 3 – Replacing Custom XML
After the custom XML file is created, it is inserted the WordprocessingML document. The following code opens the document and adds this XML file as a custom XML part.NewPart<CustomXmlPart>(); //Copy the XML into the new part. using (StreamWriter ts = new StreamWriter(customXmlPart.GetStream())) ts.Write(customXML); } }
Step 4 – Generating the Resulting Document
After the document contains the data, you save the file as seen in the following code.
protected void GenerateContractButton_Click(object sender, EventArgs e) { string strTemp = Environment.GetEnvironmentVariable("temp"); string strFileName = String.Format("{0}\\{1}.dotx", strTemp, Guid.NewGuid().ToString()); File.Copy(Server.MapPath(@"App_Data/Contract of Sale.dotx"), strFileName); GetData(); string customXml = File.ReadAllText(Server.MapPath(@"App_Data/datatemp.xml")); ReplaceCustomXML(strFileName, customXml); //Return it to the client - strFile has been updated, so return it. Response.ClearContent(); Response.ClearHeaders(); Response.AddHeader("content-disposition", "attachment; filename=Conract of Sale.dotx"); Response.ContentEncoding = System.Text.Encoding.UTF8; Response.TransmitFile(strFileName); Response.Flush(); Response.Close(); //Delete the temp file. File.Delete(strFileName); File.Delete(Server.MapPath(@"App_Data/datatemp.xml")); }
You generated the document with content controls bound to the XML data. The resulting file looks similar to the following figure.
To show how fast this solution is, executing the code to create 100 documents on a server took just 1.166 seconds.
In Creating Documents by Using the Open XML Format SDK Version 2.0 CTP (Part 1 of 3), Creating Documents by Using the Open XML Format SDK 2.0 CTP (Part 2 of 3), Creating Documents by Using the Open XML Format SDK 2.0 (Part 3 of 3), you see just a sample of ways that the Open XML Format SDK APIs can simplify integrating various data sources with programs in the 2007 version of the Microsoft Office system. With a little imagination, you can modify these applications to fit your own requirements.

Hi all!
I'm trying out some new Java code. I was surprised to find that Java
doesn't allow the static keyword for classes. How was I to implement
singleton objects then? Well, a quick web search and I've got the
answer, but now I have a few other questions on the JVM and compiler.
Let's say I have a class entirely of static methods:
public class anAPI {
static void methodA {}
static void methodB {}

I don't know the answer to your questions, but you can sidestep the questions
by defining a no-argument constructor and giving it the "private" keyword.
This way, there is no way that this class can be instantiated unless one of
its own static methods does the deed. [Well, maybe there is a cheat via
reflection.]
Your questions are still valid, and I am interested in the answers myself.

Dmitry Irlyanov commented on HARMONY-4610:
------------------------------------------
Yes, BoxPainter is the one of possible ways to resolve this issue, but placing the description
in default.css is incorrect because <img> is special tag for css and there is another
issue: our css implementation understands simple selectors only.
In general the problem is wider, as you stated: in HTML every inline element can have border
I think it is the new issue to resolve.
And implementation css-specified selectors like a[href] and img:link is another issue to implement
But I think restriction html in swing is acceptable because swing itself have much more possibilities
to process text.

Pimoroni Enviro pHAT
Enviro pHAT by Pimonori is a small and handy addition to Raspberry Pi versions 2, 3 and 4 as well as compact Raspberry Pi Zero. It features several sensors to measure various "environmental" variables such as temperature, pressure, light level and colour, 3-axis motion, compass heading, and input voltage[1]. Currently, this version is discontinued and Enviro (which is a pHat too, technically) is suggested as more advanced replacement.
Overview
Enviro pHAT is a HAT/pHAT board, which is connected to Raspberry Pi board via 40-pin GPIO header mount. Note that only difference between Hat and pHAT is that the latter has is designed especially to work Raspberry Pi Zero and fits its form factor. However, due to certain compatibility between the Raspberry Pi versions and revisions as well as other similar products (e.g. Orange, Banana Pi) it will work with them too. The pHat comes as a single board with separate pinout headers, which should be soldered prior to installation on Raspberry Pi board[2]. It uses 3 GPIO pins (#2,3,4) and 5V power and communicates over i2c interface[3]. To be mounted properly, the board should be oriented in a way so it is mounted "atop" the Raspberry Pi. To read the pHAT sensors one can use dedicated python library or dev-libs/pigpio and sys-apps/i2c-tools packages for a direct access to the GPIO pins . The following instructions are tested on Raspberry Pi 2 Model B and Enviro pHAT. Modern Enviro (not tested due to the lack of equipment) will require different python library, however, general approach would be the same.
Installation consists of the following steps:
- enabling hardware configuration in /boot/config.txt,
- checking kernel configuration and modules,
- UDEV configuration,
- software installation.
Hardware and config.txt
The pHat communicates with Raspberry Pi via I2C interface, so it should be enabled in the /boot/config.txt file, used to configure interfaces and Pi itself on the boot. Add those lines in addition to the ones present:
/boot/config.txt
## --- Enviro pHAT configuration --- ## enabling required interfaces dtparam=i2c_arm=on dtparam=i2c=on dtparam=i2c_arm_baudrate=100000
Last line sets the i2c speed with 100KHz ( default frequency) which can be changed if needed.
Configuring the kernel
One needs essentially
i2c_dev and
i2c_bcm2835 (and
i2c_bcmstb on RPi 4) modules for I2C communication. Raspberry Pi kernel distribution[4] already has necessary modules pre-compiled. Alternatively, using default kernel configuration
bcmrpi_defconfig,
bcm2709_defconfig,
bcm2711_defconfig for the appropriate target will select necessary modules. Otherwise check if you have these modules selected.
Device Drivers ---> I2C support ---> <M> I2C device interface I2C Hardware Bus support ---> <M> Broadcom BCM2835 I2C controller <M> BRCM Settop/DSL I2C controller
While the
i2c_bcm2835 (and
i2c_bcmstb on RPi 4) is normally loaded automatically during the boot,
i2c_dev is not.
Create a /etc/modules-load.d/envirophat.conf and add the module there:
root #
mkdir /etc/modules-load.d/
root #
echo "i2c_dev" >> /etc/modules-load.d/envirophat.conf
During the boot the modules the modules service will load it.
UDEV configuration
When the udev service runs it populates /dev with existing devices, including /dev/gpiomem and /dev/i2-* (normally, /dev/i2-1), which are the GPIO pins and i2c bus, which the Enviro pHat is connected to. Currently on Gentoo these devices are created with root:root ownership, however, it is more handy to change this policy so the devices are created with gpio and i2c groups, respectively, so the users can have access to them, given added to those groups.
root #
emerge acct-group/i2c acct-group/gpio
root #
echo 'KERNEL=="i2c-[0-9]*", GROUP="i2c", MODE="0660"' >> /etc/udev/rules.d/60-i2c-tools.rules
root #
echo 'KERNEL=="gpiomem", GROUP="gpio", MODE="0660"' >> /etc/udev/rules.d/60-gpiomem.rules
root #
usermod -a -G i2c gpio <your user>
If the Enviro pHat is already installed on the Raspberry Pi board at this point, one can either simply reboot, or modprobe the modules and restart the udev.
root #
modprobe i2c_dev
root #
/etc/init.d/udev restart
Check if the devices are present and have correct permissions.
root #
ls /dev/i2* -al
Software installation
Install the sys-apps/i2c-tools to check whether pHat is detected via i2c.
root #
emerge sys-apps/i2c-tools
user $
i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- 1d -- -- 20: -- -- -- -- -- -- -- -- -- 29 -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- 49 -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- 77
There is an official python package used to interact with the Enviro pHat[5], however it is not currently present in the main tree, so one may use dev-python/pip to install them.
root #
emerge dev-python/pip
Then, from the user added to the i2c and gpio groups in the previous section, install the required packages.
Currently (as of writing this page, Oct 2021) running just
pip install --user envirophatwill fail. The smbus package is not installed as a dependency and last stable version of RPi.GPIO fails with dev-lang/python:3.9, so alpha version should be manually installed instead.
user $
pip install --user RPi.GPIO==0.7.1a4
user $
pip install --user smbus
user $
pip install --user envirophat
If the
import envirophat works in python then, everything is configured correctly and works. E.g. create small python script file:
~/env_pHat_check.py
import envirophat print("Temperature reading is %2.2f°C" %(envirophat.weather.temperature()))
and check if the sensor reads the temperature outside the pHAT.
user $
python ~/env_pHat_check.py
Temperature reading is 27.30°C
The last line is an example output, your temperature will be different!
If it worked, then everything is set up for non-root user usage.

The motivation: why doing it?
Now we have a production build which works great, but when search engines look at your site they will see>
and will have no idea what this site is about and how to index it.
Good search engines like Google will render the JS and will get the right idea but there are also other benefits of having SSR.
Benefits:
– Quicker page render. Once the source code is there, with all assets (CSS, JS, Images, fonts, etc) is sent to the browser, it could start render it and it could show the site like it was already ready for use (although the events won’t be attached at this point and the site won’t be really ‘clickable’ the user will at least see a fully rendered site which gives him the perception of a fully ready site)
– SCO benefits
– Pages could be pre-rendered on the server and cached.
So. let’s dive into this:
SSR Checklist
This might be more complicated task that we would expect so let’s outline a checklist of what have to be done to achieve SSR:
- Fetch all GraphQL queries on the backend before start generating the source code.
Some components rely on having their data fetched from GraphQL before render.
For example, If you remember we dynamically fetch the page components layout from GraphQL so in order to serve the page source, we have to make the page query and return the list of all components for the current route. For example the ‘/home’ page should hare 2 components: header and Home components.
- Make sure that bundle splitting will continue work.
- Fetch only assets that are necessary to be served for each particular route.
We have to pre-render the page, and figure out which JS and CSS bundles should be added in the source code. For example for the home page ‘/home’ we have to include:
<script src=’dist/header.js’/></script>
<link href=”/dist/header.css”/><script src=’dist/home.js’/></script>
<link href=”/dist/home.css”/>
- Finally fetch the source code string and send it to the browser.
Adding server side rendering (SSR).
Let’s start with adding the server side rendering script, and the script that will run it.
Adding ssr build script
./package.json
"scripts": { "start-cli": "webpack-dev-server --hot --history-api-fallback --config webpack.cli.config.js", "start-api": "babel-node server-api.js", "start-middleware": "babel-node server-middleware.js", "clean": "rm -rf ./dist ./server-build", "lint": "eslint .", "build-dev": "webpack --mode development", "build-prod": "webpack --config webpack.prod.config.js", "build-ssr": "webpack --config webpack.server.config.js", "run-server": "node ./server-build/server-bundle.js", "start": "yarn clean; yarn build-prod; yarn build-ssr; yarn run-server" },
what we just did:
– (line 9) adding
build-ssr script to bundle the express server into a executable JS
– (line 10) adding
start script to run the express server which will:
1. send the page source to the browser.
2. serve the static production bundle.
3. serve all other assets (images, fonts, etc)
– remove
run-prod-server and
build-and-run-prod-server since we are replaced them with the new scripts.
– add `server-build` to the cleaning script since this is the location where the server bundle will be dumped.
Creating SSR config
Since most of the configuration will be similar to the production config, let’s start by copying the production config into a new file called ./webpack.ssr.config.js and do some adjustments specific for SSR.
./webpack.ssr.config.js
const path = require('path'); const webpack = require('webpack'); const nodeExternals = require('webpack-node-externals'); let config = require('./webpack.base.config.js'); const MiniCssExtractPlugin = require("mini-css-extract-plugin"); const OptimizeCSSAssetsPlugin = require("optimize-css-assets-webpack-plugin"); config.mode = "production"; config.devtool = ""; config.target = "node"; config.externals = [nodeExternals()]; config.entry = { server: './ssr-server.js' } config.output = { filename: '[name]-bundle.js', path: path.resolve(__dirname, 'server-build') } config.module.rules[1].use[0] = MiniCssExtractPlugin.loader; config.plugins = [ ... config.plugins, ... [ new MiniCssExtractPlugin({ filename: "[name].css" }), new OptimizeCSSAssetsPlugin({}), // on the server we still need one bundle new webpack.optimize.LimitChunkCountPlugin({ maxChunks: 1 }) ] ]; module.exports = config;
what we just did:
– (line 10) we told Webpack that this bundle will not run in the browser but in the ‘node’ environment.
– (line 11) we aded Webpack Node Externals which will remove the node_modules which we don’t need when execute in ‘node’ environment.
– (line 14) specifies a new entry point for the SSR, that will run the express server (similar to the one that we built for production)
– (line 31) on the server side we still need one bundle file.
Now let’s add the missing module:
yarn add webpack-node-externals --dev
Adding Express server
This is going to be the same Express server that we added in the previous chapter to serve the production requests, but settings will be much more complex to fit the SSR needs. Create ssr-server.js with the following content:
./ssr-server.js
import React from 'react'; import express from 'express'; import App from './src/components/App/ssr-index'; import Loadable from 'react-loadable'; import manifest from './dist/loadable-manifest.json'; import { getDataFromTree } from "react-apollo"; import { ApolloClient } from 'apollo-client'; import { InMemoryCache } from 'apollo-cache-inmemory'; import { renderToStringWithData } from "react-apollo" import { createHttpLink } from 'apollo-link-http'; import { getBundles } from 'react-loadable/webpack'; const PORT = process.env.PROD_SERVER_PORT; const app = express(); app.use('/server-build', express.static('./server-build')); app.use('/dist', express.static('dist')); // to serve frontent prod static files app.use('/favicon.ico', express.static('./src/images/favicon.ico')); app.get('/*', (req, res) => { const GRAPHQL_URL = process.env.GRAPHQL_URL; const client = new ApolloClient({ ssrMode: true, link: createHttpLink({ uri: GRAPHQL_URL, fetch: fetch, credentials: 'same-origin', headers: { cookie: req.header('Cookie'), }, }), cache: new InMemoryCache() }); // Prepare to get list of all modules that have to be loaded for this route const modules = []; const mainApp = ( <Loadable.Capture report={moduleName => modules.push(moduleName)}> <App req={req} client={client} /> </Loadable.Capture> ); // Execute all queries and fetch the results before continue getDataFromTree(mainApp).then(() => { // Once we have the data back, this will render the components with the appropriate GraphQL data. renderToStringWithData().then( (HTML_content) => { // Extract CSS and JS bundles const bundles = getBundles(manifest, modules); const cssBundles = bundles.filter(bundle => bundle && bundle.file.split('.').pop() === 'css'); const jsBundles = bundles.filter(bundle => bundle && bundle.file.split('.').pop() === 'js'); res.status(200); res.send(`< --> ${ cssBundles.map( (bundle) => (` <link href="${bundle.publicPath}" rel="stylesheet" as="style" media="screen, projection" type="text/css" charSet="UTF-8" />`)).join('\n') } <!-- Page specific JS bundle chunks --> ${jsBundles .map(({ file }) => `<script src="/dist/${file}"></script>`) .join('\n')} <!-- =========================== --> </head> <body cz- <div id="root"/> ${HTML_content} </div> <script> window.__APOLLO_STATE__=${JSON.stringify(client.cache.extract())}; </script> <script src="/dist/main-bundle.js"></script> </body> </html>`); res.end(); }); }).catch( (error) => { console.log("ERROR !!!!", error); }); }); Loadable.preloadAll().then(() => { app.listen(PORT, () => { console.log(`😎 Server is listening on port ${PORT}`); }); });
what we just did:
Clearly a lot of stuff so let’s take one step at a time.
– We created express server similar to the one we did for production in the previous chapter.
– (line 13,14) we created the server, telling it to run on the port that we will specify in the .env file later in this tutorial.
– (line 20) we are telling Express to listen to any request pattern, except for these above described in
app.use
– (line 53) sending the html to the browser.
– We fetch the data for all queries in the app before continue.
– (lines 21-33) We created the Apollo client.
– (line 44) calling
getDataFromTree from
react-apollo will walk through the React tree to find any components that make GraphQL requests. It will execute the queries and return a promise.
– (line 46) calling
renderToStringWithData will render the app with the necessary GraphQL data.
– (line 90) since we already fetched all data, we are going to stringify it, and attach it to the
window object so it could be re-used on the client side. this part is very important. It does so called Store hydration. If we miss it we will end up making twice more queries to GraphQL: one set on the server side, and one set on the client side.
– We get a list of all components that will have to render for the particular route, and create appropriate SCRIPT and LINK tags to load JS and CSS only for these components.
– (line 38) we use
Loadable.Capture from
react-loadable to create an array of all components that exist in the particular route and store it in
modules = []
– (lines 48 – 50) Will extract the CSS and JS bundle file lists
– ( lines 67 – 83) will traverse CSS and JS arrays and will create the appropriate CSS and JS tags to include the components that are about to render in this particular route.
– (line 104) is going to pre-load all the components before continue so we won’t see just the “loading” component.
One very important step that could be easily forgotten is to add
react-loadable/babel plug-in into .babelrc otherwise we are going to wonder why the assets list is never created.
./.babelrc
{ "presets": [ "@babel/preset-env", "@babel/preset-react" ], "plugins": [ "@babel/plugin-syntax-dynamic-import", "react-loadable/babel" ] }
Also let’s add
PROD_SERVER_PORT to our .env file
./env
APP_NAME=Webpack React Tutorial GRAPHQL_URL= PROD_SERVER_PORT=3006
and make it available on the front end so Express could pick it up.
./getEnvironmentConstants.js
const fs = require('fs'); // Load environment variables from these files const dotenvFiles = [ '.env' ]; // expose environment variables to the frontend const frontendConstants = [ 'APP_NAME', 'GRAPHQL_URL', 'PROD_SERVER_PORT' ]; function getEnvironmentConstants() { dotenvFiles.forEach(dotenvFile => { if (fs.existsSync(dotenvFile)) { require('dotenv-expand')( require('dotenv').config({ path: dotenvFile, }) ); } }); const arrayToObject = (array) => array.reduce((obj, item, key) => { obj[item] = JSON.stringify(process.env[item]); return obj }, {}) return arrayToObject(frontendConstants); } module.exports = getEnvironmentConstants;
Adding ./components/App/ssr-index.js
Now if we look again at ./ssr-server.js (line 3) we will see that we are not pointing the App module to the index.js but to ssr-index.js instead, and the reason for this is that on the server things will be slightly different.
First we can’t use
BrowswerRouter because clearly there is no browser in a node environment. We have to use
StaticRouter instead.
Second, we don’t need to instantiate a new ApolloClient since we already did this in ./ssr-server.js file above. We are just going to pass it as a
client param.
With that being said, let’s go ahead and create:
./components/App/ssr-index.js
import React from 'react'; import PageLayout from '../../containers/PageLayout'; import { StaticRouter, Route, Switch } from 'react-router-dom'; import { ApolloProvider } from 'react-apollo'; import { Provider } from 'react-redux'; import { createStore} from 'redux'; import reducers from '../../reducers'; import fetch from 'isomorphic-fetch'; import styles from './styles.scss'; const store = createStore(reducers, {}); export default ( {req, client} ) => { const context = {}; return ( <div className={styles.appWrapper}> <Provider store={store}> <ApolloProvider client={client}> <StaticRouter location={ req.url } context={context}> <Switch> <Route exact path="*" component={PageLayout} /> </Switch> </StaticRouter> </ApolloProvider> </Provider> </div> ); }
DOM Hydration
We did almost all necessary steps for SSR but if we run the app we will see that we are not taking the advantage of the server side rendering and the app will reload on the client side.
We still need to do two important things: DOM hydration and Store rehydration.
DOM hydration is going to attach the events to the existing HTML layout returned from the SSR. Adding it is pretty straight forward: we have to replace ReactDOM.render with ReactDOM.hydrate.
./src/index.js
import React from 'react'; import ReactDOM from 'react-dom'; import App from './components/App'; ReactDOM.hydrate(<App/>, document.getElementById('root')); if (module.hot) { module.hot.accept(); }
Apollo store rehydration
This is also pretty straight forward. If we go back in this tutorial we could haver recall that when we create ./ssr-server.js we fetched the data for all queries, and attached it to the window object (line 90)
Now, let’s use this:
./src/components/App/index.js
import React from 'react'; import PageLayout from '../../containers/PageLayout'; import { ApolloProvider } from 'react-apollo'; import { ApolloClient } from 'apollo-client'; import { HttpLink } from 'apollo-link-http'; import { InMemoryCache } from 'apollo-cache-inmemory'; import { BrowserRouter as Router, Route, Switch } from 'react-router-dom'; import { Provider } from 'react-redux'; import { createStore} from 'redux'; import reducers from '../../reducers'; const styles = require('./styles.scss'); const store = createStore(reducers, {}); export default ( {req} ) => { const GRAPHQL_URL = process.env.GRAPHQL_URL; const client = new ApolloClient({ link: new HttpLink({ uri: GRAPHQL_URL }), cache: new InMemoryCache().restore(window.__APOLLO_STATE__), }); return ( <div className={styles.appWrapper}> <Provider store={store}> <ApolloProvider client={client}> <Router> <Switch> <Route exact path="*" component={PageLayout} /> </Switch> </Router> </ApolloProvider> </Provider> </div> ); }
Ready for a test flight
Finally we are ready to test flight this beast.
yarn start and navigate the browser there
localhost:3006/home
The response time should be mind blowing with all prod settings and SSR in place.
Open the source code and you should see something like this:
< --> <link href="/dist/2.css" rel="stylesheet" as="style" media="screen, projection" type="text/css" charSet="UTF-8" /> <link href="/dist/3.css" rel="stylesheet" as="style" media="screen, projection" type="text/css" charSet="UTF-8" /> <!-- Page specific JS bundle chunks --> <script src="/dist/2-bundle.js"></script> <script src="/dist/3-bundle.js"></script> <!-- =========================== --> </head> <body cz- <div id="root"/> <div class="App-appWrapper" data-<div><div><div class="Header-wrapper"><h2> <!-- -->Webpack React Tutorial<!-- --> </h2><ul><li><a href="/home">HOME</a></li><li><a href="/greetings">GREETINGS</a></li><li><a href="/dogs-catalog">DOGS CATALOG</a></li><li><a href="/about">ABOUT</a></li></ul></div></div><div><div class="Home-wrapper">This is my home section!</div></div></div></div> </div> <script> window.__APOLLO_STATE__={"Page:home":{"id":"home","url":"/home","layout":[{"type":"id","generated":true,"id":"Page:home.layout.0","typename":"PageLayout"},{"type":"id","generated":true,"id":"Page:home.layout.1","typename":"PageLayout"}],"__typename":"Page"},"Page:home.layout.0":{"span":"12","components":[{"type":"id","generated":true,"id":"Page:home.layout.0.components.0","typename":"PageComponents"}],"__typename":"PageLayout"},"Page:home.layout.0.components.0":{"name":"Header","__typename":"PageComponents"},"Page:home.layout.1":{"span":"12","components":[{"type":"id","generated":true,"id":"Page:home.layout.1.components.0","typename":"PageComponents"}],"__typename":"PageLayout"},"Page:home.layout.1.components.0":{"name":"Home","__typename":"PageComponents"},"ROOT_QUERY":{"getPageByUrl({\"url\":\"/home\"})":{"type":"id","generated":false,"id":"Page:home","typename":"Page"}}}; </script> <script src="/dist/main-bundle.js"></script> </body> </html>
As you might notice, (lines 15-37) that only the bundles for the components that we need there are loaded.
Also you will see the Apollo client (The GraphQL queries) serialized and attached to the window object (line 44) which we are using to re-hydrate the client and avoid another GraphQL call.
Well, this could have been as far as a production ready stack, but two important things are missing: tests and caching. But this is good enough as an end of this chapter. | https://www.toni-develops.com/2018/09/10/server-side-rendering/ | CC-MAIN-2021-43 | en | refinedweb |

Debugging tf2 problems
Goal: Learn how to use a systematic approach for debugging tf2 related problems.
Tutorial level: Advanced
Time: 10 minutes
Contents
Background
This tutorial walks you through the steps to debug a typical tf2 problem.
It will also use many of the tf2 debugging tools, such as
tf2_echo,
tf2_monitor, and
view_frames.
This tutorial assumes you have completed the learning tf2 tutorials.
Debugging example
1 Setting and starting the example
For this tutorial we will set up a demo application that has a number of problems. The goal of this tutorial is to apply a systematic approach to find and tackle these problems. First, let’s create the source file.
Go to the
learning_tf2_cpp package we created in tf2 tutorials.
Inside the
src directory make a copy of the source file
turtle_tf2_listener.cpp and rename it to
turtle_tf2_listener_debug.cpp.
Open the file using your preferred text editor, and change line 67 from
std::string to_frame_rel = "turtle2";
to
std::string to_frame_rel = "turtle3";
and change
lookupTransform() call in lines 75-79 from
try { transformStamped = tf_buffer_->lookupTransform( toFrameRel, fromFrameRel, tf2::TimePointZero); } catch (tf2::TransformException & ex) {
to
try { transformStamped = tf_buffer_->lookupTransform( toFrameRel, fromFrameRel, this->now()); } catch (tf2::TransformException & ex) {
And save changes to the file.
In order to run this demo, we need to create a launch file
start_tf2_debug_demo.launch.py in the
launch subdirectory of package
learning_tf2_cpp:
from launch import LaunchDescription from launch.actions import DeclareLaunchArgument from launch.substitutions import LaunchConfiguration from launch_ros.actions import Node def generate_launch_description(): return LaunchDescription([ DeclareLaunchArgument( 'target_frame', default_value='turtle1', description='Target frame name.' ), Node( package='turtlesim', executable='turtlesim_node', name='sim', output='screen' ), Node( package='learning_tf2_cpp', executable='turtle_tf2_broadcaster', name='broadcaster1', parameters=[ {'turtlename': 'turtle1'} ] ), Node( package='learning_tf2_cpp', executable='turtle_tf2_broadcaster', name='broadcaster2', parameters=[ {'turtlename': 'turtle2'} ] ), Node( package='learning_tf2_cpp', executable='turtle_tf2_listener_debug', name='listener_debug', parameters=[ {'target_frame': LaunchConfiguration('target_frame')} ] ), ])
Don’t forget to add the
turtle_tf2_listener_debug executable to the
CMakeLists.txt and build the package.
Now let’s run it to see what happens:
ros2 launch learning_tf2_cpp start_tf2_debug_demo.launch.py
You will now see that the turtlesim came up.
At the same time, if you run the
turtle_teleop_key in another terminal window, you can use the arrow keys to drive the
turtle1 around.
ros2 run turtlesim turtle_teleop_key
You will also notice that there is a second turtle in the lower, left corner. If the demo would be working correctly, this second turtle should be following the turtle you can command with the arrow keys. However, it is not the case because we have to solve some problems first. You should notice the following message:
[turtle_tf2_listener_debug-4] [INFO] [1630223454.942322623] [listener_debug]: Could not transform turtle3 to turtle1: "turtle3" passed to lookupTransform argument target_frame does not exist
2 Finding the tf2 request
Firstly, we need to find out what exactly we are asking tf2 to do.
Therefore, we go into the part of the code that is using tf2.
Open the
src/turtle_tf2_listener_debug.cpp file, and take a look at line 67:
std::string to_frame_rel = "turtle3";
and lines 75-79:
try { transformStamped = tf_buffer_->lookupTransform( toFrameRel, fromFrameRel, this->now()); } catch (tf2::TransformException & ex) {
Here we do the actual request to tf2.
The three arguments tell us directly what we are asking tf2: transform from frame
turtle3 to frame
turtle1 at time
now.
Now, let’s take a look at why this request to tf2 is failing.
3 Checking the frames
Firstly, to find out if tf2 knows about our transform between
turtle3 and
turtle1, we will use
tf2_echo tool.
ros2 run tf2_ros tf2_echo turtle3 turtle1
The output tells us that frame
turtle3 does not exist:
[INFO] [1630223557.477636052] [tf2_echo]: Waiting for transform turtle3 -> turtle1: Invalid frame ID "turtle3" passed to canTransform argument target_frame - frame does not exist
Then what frames do exist?
If you like to get a graphical representation of this, use
view_frames tool.
ros2 run tf2_tools view_frames
Open the generated
frames.pdf file to see the following output:
So obviously the problem is that we are requesting transform from frame
turtle3, which does not exist.
To fix this bug, just replace
turtle3 with
turtle2 in line 67.
And now stop the running demo, build it, and run it again:
ros2 launch turtle_tf2 start_debug_demo.launch.py
And right away we run into the next problem:
[turtle_tf2_listener_debug-4] [INFO] [1630223704.617382464] [listener_debug]: Could not transform turtle2 to turtle1: Lookup would require extrapolation into the future. Requested time 1630223704.617054 but the latest data is at time 1630223704.616726, when looking up transform from frame [turtle1] to frame [turtle2]
4 Checking the timestamp
Now that we solved the frame name problem, it is time to look at the timestamps.
Remember, we are trying to get the transform between
turtle2 and
turtle1 at the current time (i.e.,
now).
To get statistics on the timing, call
tf2_monitor with corresponding frames.
ros2 run tf2_ros tf2_monitor turtle2 turtle1
The result should look something like this:
RESULTS: for turtle2 to turtle1 Chain is: turtle1 Net delay avg = 0.00287347: max = 0.0167241 Frames: Frame: turtle1, published by <no authority available>, Average Delay: 0.000295833, Max Delay: 0.000755072 All Broadcasters: Node: <no authority available> 125.246 Hz, Average Delay: 0.000290237 Max Delay: 0.000786781
The key part here is the delay for the chain from
turtle2 to
turtle1.
The output shows there is an average delay of about 3 milliseconds.
This means that tf2 can only transform between the turtles after 3 milliseconds are passed.
So, if we would be asking tf2 for the transformation between the turtles 3 milliseconds ago instead of
now, tf2 would be able to give us an answer sometimes.
Let’s test this quickly by changing lines 75-79 to:
try { transformStamped = tf_buffer_->lookupTransform( toFrameRel, fromFrameRel, this->now() - rclcpp::Duration::from_seconds(0.1)); } catch (tf2::TransformException & ex) {
In the new code we are asking for the transform between the turtles 100 milliseconds ago. It is usual to use a longer periods, just to make sure that the transform will arrive. Stop the demo, build and run:

And you should finally see the turtle move!
That last fix we made is not really what you want to do, it was just to make sure that was our problem. The real fix would look like this:
try { transformStamped = tf_buffer_->lookupTransform( toFrameRel, fromFrameRel, tf2::TimePointZero); } catch (tf2::TransformException & ex) {
Or like this:
try { transformStamped = tf_buffer_->lookupTransform( toFrameRel, fromFrameRel, tf2::TimePoint()); } catch (tf2::TransformException & ex) {
You can learn more about timeouts in the Learning about tf2 and time tutorial, and use them as below:

Much Ado About Monads – Reader Edition
In the previous post, we talked a bit about the State Monad, what it is and how you could use it today in your F# application. But, with any new piece of information such as this, it should be taken in context, and there are other patterns as well when dealing with a multi-paradigm language such as F#. We also talked about how the State Monad might not have been the best choice for modeling our web scripting DSL as our browser state is encapsulated in the Browser class, and once it is set, it doesn’t change. With that, we could turn our eyes to using the Reader Monad as we read from our environment.
Reading From Our Environment
If you recall from the previous post, we had a simple example of keeping track of browser state our ultimate goal was to have the state managed for us underneath the covers. When dealing with the State Monad, each bind call would not only return us our calculated value, but also our new state as well. In this case, this was wasteful due to the fact that once the state was set, it never changed, as the state was fully encapsulated inside the Browser object. So, our ultimate goal would be instead to have our environment set once and then read from it implicitly. We still want to keep what we have here in terms of our script, but change the underlying mechanism for how it happens:
[<Fact>] let ``Can find CodeBetter on Bing``() = reader { do! openPage "" do! enterText "q" "CodeBetter" do! clickButton "go" let! result = containsText "CodeBetter" isTrue result do! closePage } |> runScript
As the State Monad allows us to plumb a piece of mutable state through our code, the Reader Monad helps us pass immutable state around underneath the covers. This immutable state could be anything, such as configuration data, environment variables and so on. Instead of relying on a static dependency like the Environment or ConfigurationManager class within .NET, you might imagine having some abstraction passed around implicitly inside the Reader Monad. This way, our testing scenarios become easier as we don’t have to try and mock static calls. Just as well, you can abstract other items behind the scenes as well such as locks, transactions and so forth.
Now that we defined the problem and generally speaking what the Reader Monad is, let’s go ahead and define it. To do this, we’ll need an overarching container to describe this environment that we’re maintaining. In this case, we have the Reader<’r,’a> type which the ‘a is our result type and the ‘r is our type of our environment. This Reader type has a constructor that takes a function which takes our environment parameter and returns our result.
type Reader<'r,'a> = Reader of ('r -> 'a)
In addition, we’ll need a way to run our Reader so that we can provide it with our environment and return our calculated value. Let’s create a function called runReader which takes our Reader and our environment, and returns our calculated value.
// val runReader : Reader<'a,'b> -> 'a -> 'b let runReader (Reader r) env = r env
Before we get to some of our helper functions, let’s get to the monad part.. You should recall that our return function must have the following signature, keeping in mind that M defined below is our monadic type.
val returnF : 'a -> M<'a>
In the case of the Reader Monad, it should look like this where we take in a value and return a Reader of our environment and return value.
val returnF : 'a -> Reader<'r,'a>
Now, let’s look at the implementation. In the case of return, we simply return a Reader with the constructed function taking in any value and returning our calculated value. Our return value should be the same no matter what the environment value that is passed in, so we can safely ignore it.
let returnF a = Reader (fun _ -> a)
Next, we need to define the bind operation. As you may recall, our bind operation must look like the following code, keeping in mind that M defined below is our monadic type.
val bind : M<'a> -> ('a -> M<'b>) -> M<'b>
In the case of our Reader Monad, it should look like this:
val bind : Reader<'r,'a> -> ('a -> Reader<'r, 'b>) -> Reader<'r, 'b>
Let’s break this down a little more to show what is really going on underneath the covers.
val bind : ('r -> 'a) -> ('a -> 'r -> 'b) -> ('r -> 'b)
What we see is that the first argument is a function which takes our environment and produces a our calculated value. Our second argument is a function that takes a value and our environment and then generates our new calculated value. What our goal is to combine these two functions into a larger function from our environment to our new calculated value.
let bind m k = Reader (fun r -> runReader (k (runReader m r)) r)
What we did above is make our environment available to both the inside execution and outside execution of our runReader. Taking these two functions together, the bind and return, we can now create a builder which can provide us some syntactic sugar when writing functions using the Reader Monad.
type ReaderBuilder() = member this.Return(a) = Reader (fun _ -> a) member this.Bind(m, k) = Reader (fun r -> runReader (k (runReader m r)) r)
By no means are these two the only methods that we could implement, and in fact, there are quite a few more we could do, but that’s for the next post. Now, we need to revisit some helper functions that are necessary when dealing with the Reader Monad. For example, how can we get our current environment? All we have to do is ask:
// val ask : Reader<'r,'r> let ask = Reader (id)
What this function simply does is return our environment to us by using the id function, which is to say that you return what you are given. As you recall, our Reader has a constructing function with ‘r –> ‘a and in this case, the ‘a will also be the ‘r. Also, instead of just returning our environment, what about also providing a function that applies a function over our environment as well? Let’s implement that as asks:
// val asks : ('r -> 'a) -> Reader<'r,'a> let asks f = reader { let! r = ask return (f r) }
One more function to consider is the local function. This function allows us to execute a given function on a modified environment. The local function takes a function which modifies the environment as well as a reader to run, and the returns a reader with the changed environment. This doesn’t change the environment globally, but gives you a way to locally change the environment and execute a function against it.
// val local : ('r1 -> 'r2) -> Reader<'r1,'a> -> Reader<'r2,'a> let local f m = Reader (f >> runReader m)
The function implementation is fairly straight forward as it returns a Reader with the constructing function that first executes the f function on the environment, and then we run our Reader parameter against this new environment value. Now that we’ve got some basic ideas, let’s venture into a scenario or two.
A Scenario
Let’s look at a scenario for how we might use the Reader Monad. One interesting example came from Greg Neverov to handle locks as the environment using this monad. Let’s look at that a little deeper. In order to support such a scenario, we’d need a few pieces. First, we would need the ability to run a particular reader while handling the locking behind the scenes. Let’s take a look at what that would entail:
open System.Threading let tryRunLock lock m = let lock = box lock let lockTaken = ref false Monitor.Enter(lock, lockTaken) match !lockTaken with | true -> try Some(runReader m lock) finally Monitor.Exit lock | _ -> None
Our tryRunLock function takes a lock and our reader that we wish to execute. We call Monitor.Enter with our lock that has been boxed and a flag to determine whether the lock has been taken. We then check whether the lock has been taken and if so, we return Some of our Reader result, else we return None to indicate a failure.
Next, we need the ability to notify all waiting threads that there has been a change in our state. To do that, we must call the Monitor.PulseAll method.
let pulseAll = Reader Monitor.PulseAll
Here we partially applied the environment to the Monitor.PulseAll method call so there was no need to specify the argument explicitly. After this, we need one more function which is to release the lock and block the current thread until we can reacquire it. To do this, we simply call the Monitor.Wait method.
let wait = Reader (Monitor.Wait >> ignore)
Now we can apply these in a scenario such as moving items between two Stacks in which we pop from one and push to another. Let’s turn our attention first to the pop function which takes our Stack, and then while the Stack count is zero, then it blocks and waits. When there is something in the Stack, we simply call Pop and return the value.
open System.Collections.Generic let pop (stack:Stack<_>) = reader { while stack.Count = 0 do return! wait return stack.Pop() }
Note that there is a while loop here which we will work on implementing in the next post. We can now turn our attention to the push function which takes our Stack and a value to push. If our Stack count is zero, then we call pulseAll which indicates there is a state change. After this we simply push the value onto the Stack.
let push (stack:Stack<_>) x = reader { if stack.Count = 0 then return! pulseAll do stack.Push(x) }
Moving on, we can now define a function called move which takes a value from one Stack and moves it to another using locks behind the scenes.
// Our lock object let lockObj = new obj() let move s1 s2 = reader { let! x = pop s1 do! push s2 x return x } |> tryRunLock lockObj
We can run this through to verify our behavior such as the following:
> let s1 = new Stack<int>([1..3]) > let s2 = new Stack<int>() > let moved = move s1 s2;; val s1 : Stack<int> val s2 : Stack<int> val moved : int option = Some 3 > s2;; val it : Stack<int> = seq [3]
As you can see, it took the last value from our s1 and moved it to the s2 and did so using locks in a composable fashion. Let’s look at our original example again.
Back to the Web Example
Revisiting our web example again, we can rewrite much of what we had before using the State Monad as the Reader Monad. To do this takes very little effort. First, we must instead of calling getState in the State Monad, we simply ask for the environment and then call the appropriate method on our Browser object. For example, we can implement the openPage function as follows:
let openPage (url:string) = reader { let! (browser : Browser) = ask return browser.GoTo url }
We could have also implemented the openPage using the standard Reader constructor as well:
let openPage (url:string) = Reader (fun (browser : Browser) -> browser.GoTo url)
Just as well, we could utilize the asks function as well to execute a function against our environment. We could rewrite our openPage such as this to take advantage:
let openPage (url:string) = reader { return! asks (fun (browser : Browser) -> browser.GoTo url) }
But, in order to make this happen, we need to implement another method on our ReaderBuilder that we implemented above. The method required is called ReturnFrom which basically does nothing to our Reader but return it.
type ReaderBuilder() = ... member this.ReturnFrom((a:Reader<'r,'a>)) = a ...
I’ll cover the rest of the other methods you can introduce to your builders in order to take advantage of such things as try/catch, try/finally, using, for, while, etc in the next post. Following the same pattern on all the other methods from the previous post, we can now execute our script and it will work much as it did for the State Monad.
[<Fact>] let ``Can find CodeBetter on Bing``() = reader { do! openPage "" do! enterText "q" "CodeBetter" do! clickButton "go" let! result = containsText "CodeBetter" isTrue result do! closePage } |> runScript
By using this design pattern, we have a nice way of abstracting this environment that we can create a very flexible syntax. But with any pattern, it’s about finding the right applications for it.
Conclusion
Once again, by looking at Monads, we can discover what abstractions can be accomplished with them, but just as well, what they are not about. Certainly, functional languages don’t need them, but they certainly can be quite useful. When we find repeated behavior, such as maintaining state, this abstraction can be quite powerful. Practically though in languages such as F#, they can be useful, but other patterns and abstractions can as well. Find the right abstraction and use it.
In the next post, we’ll cover the additional methods you can add to your builder to enable such things as while loops, for loops, try/catch blocks, and so on before wrapping up this series again. | https://weblogs.asp.net/podwysocki/much-ado-about-monads-reader-edition | CC-MAIN-2021-43 | en | refinedweb |
First Look: InterSystems IRIS Native API for Python
This First Look guide explains how to access InterSystems IRIS® globals from a Python application using the InterSystems IRIS Native functionality. IRIS Native also allows you to run ObjectScript methods, functions, and routines. Python 3

.
Introduction to InterSystems IRIS Storage Structures
InterSystems IRIS provides.
Exploring IRIS Native for Python
At this point, you are ready to experiment with IRIS Native. The following brief demo shows you how to work with IRIS Native in a simple Python application.
Want to try an online video-based demo of the InterSystems Native API for Python? Check out the Python QuickStart
!
Before You Begin
To use the procedure, you need a running instance of InterSystems IRIS and a system to work on, with Python 3 with the PIP utility, and your favorite Python IDE. (On Windows systems, make sure the Python interpreter is included in your PATH environment variable.) Python IDEs
in the same document.
Install the Native API Package
Before running the sample Python program, you need to use the PIP package manager to install the irispython wheel file, which is available at install-dir\dev\python, where install-dir is the installation directory for your instance of InterSystems IRIS. For example, you might run:
pip install intersystems_irispython-3.2.0-py3-none-any.whl
The IRIS Native Application
Now that you’ve created your project, you will create a small application that demonstrates a few of the features of the Native API.
In your IDE, create a new source file named IRISNative.py.
Paste the following code into IRISNative.py, substituting the connection information for your InterSystems IRIS instance
. You can specify the USER namespace as shown, or you can choose another that you have created on your instance:
import irisnative # Modify connection info based on your environment ip = "127.0.0.1" port = 1972 namespace = "USER" username = "_SYSTEM" password = "SYS" # create database connection and IRIS instance connection = irisnative.createConnection(ip,port,namespace,username,password) dbnative = irisnative.createIris(connection) print("[1. Setting and getting a global]") # setting and getting a global # ObjectScript equivalent: set ^testglobal("1") = 8888 dbnative.set(8888, "testglobal", "1") # ObjectScript equivalent: set globalValue = $get(^testglobal("1")) globalValue = dbnative.get("testglobal","1") print("The value of testglobal is ", globalValue) print() print("[2 Iterating over a global]") # modify global to iterate over # ObjectScript equivalent: set ^testglobal("1") = 8888 # ObjectScript equivalent: set ^testglobal("2") = 9999 dbnative.set(8888, "testglobal", "1") dbnative.set(9999, "testglobal", "2") Iter = dbnative.iterator("testglobal") print("walk forwards") for subscript, value in Iter.items(): print("subscript= {}, value={}".format(subscript, value)) print() print("[3. Calling a class method]") # calling a class method # ObjectScript equivalent: set returnValue = ##class(%Library.Utility).Date(5) returnValue = dbnative.classMethodValue("%Library.Utility", "Date", 5) print(returnValue) # close connection connection.close() Python application using IRIS Native.
Globals in ObjectScript begin with the caret character ( ^ ). This is not a requirement in your Python applications that use the InterSystems IRIS Native API.

Finding where two lines cross can be done by calculating their cross product. The code below returns an optional tuple containing the X and Y intersection points, or nil if they don’t cross at all.
Note: Core Graphics doesn’t give us a
CGLine type, so you’ll need pass this four points: where the first line starts and ends, and where the second line starts and ends.
func linesCross(start1: CGPoint, end1: CGPoint, start2: CGPoint, end2: CGPoint) -> (x: CGFloat, y: CGFloat)? { // calculate the differences between the start and end X/Y positions for each of our points let delta1x = end1.x - start1.x let delta1y = end1.y - start1.y let delta2x = end2.x - start2.x let delta2y = end2.y - start2.y // create a 2D matrix from our vectors and calculate the determinant let determinant = delta1x * delta2y - delta2x * delta1y if abs(determinant) < 0.0001 { // if the determinant is effectively zero then the lines are parallel/colinear return nil } // if the coefficients both lie between 0 and 1 then we have an intersection let ab = ((start1.y - start2.y) * delta2x - (start1.x - start2.x) * delta2y) / determinant if ab > 0 && ab < 1 { let cd = ((start1.y - start2.y) * delta1x - (start1.x - start2.x) * delta1y) / determinant if cd > 0 && cd < 1 { // lines cross – figure out exactly where and return it let intersectX = start1.x + ab * delta1x let intersectY = start1.y + ab * delta1y return (intersectX, intersectY) } } // lines don't cross return nil }

SHET
SHET.
The majority of the code is available on the house's GitHub page.
The rest of this document is a (still unfinished) write-up of what we did.
Introduction
This is the story of a group of Computer Science undergraduates and our quest to
avoid work at all costs by building a home
automation system for their
house. Its a tale of ridiculous hacks, novel architectures and, above all,
liberal use of blu-tack fun.
After meeting in our first year we decided we wanted to try and do something cool with our house. The resulting list of ideas was laughably ambitious, especially given that we couldn't really do anything to the building itself and that we also had to eat.
Two years and many hacks later and we have a remarkably feature-rich home automation system. We've got automated lights, media control, a washing machine that emails you, a recipe-browsing control panel, an electronic door-stop, a doop button and more! The whole thing is built on our own custom home automation system, 'SHET', and designed to be extremely hackable.
In The Beginning... (Motivation)
We started our grand plan listing off all manner of things we wanted our system to do. Apart from the slight concern of how we'd afford food after building this system, we also had to consider the wrath of the landlord. Whatever we built would have to be easily removed and not do (too much) damage to the house.
Our search for a house was a mixed affair. In the 3rd house with more mould than wallpaper, Tom was excited to discover one who's electricity meter had a light that flashed at a rate proportional to usage. Despite this critically important feature, we eventually decided to go somewhere else and landed up at 18 South Grove.
With our house found, we started thinking about what we wanted our home automation system to be like. Looking around the web we discovered that most systems were pretty bad. They generally were pretty clunky and seemingly designed for a bygone era or extremely limited and closed. We wanted something that was really flexible, hackable and actually nice to work with.
Seeing as we are all students, things were obviously going to have to be cheap. This ruled out a lot of options where specialist hardware was needed. Electronics knowledge (for all but Tom) was also in short supply which meant that the system would have to be electrically fairly simple. It also meant that high-voltage stuff was completely out of bounds.
SHET House Event Tunnelling (Designing the Software)
Our reaction to the problem of making the system hackable was a somewhat obvious one for any self-respecting *nix user:
"Shell scripts!"
- Jonathan
Luckily, sanity prevailed but the idea stuck. We decided that having a
file system-like tree containing all the controllable things in our
house was a cool way of doing things. For example,
/lounge/lights would control the lights in the lounge and
/jonathan/sound/speakers/volume would control the volume of
Jonathan's speakers.
With the idea of a 'file-system' full of real things, we set out to think about how this could work. We eventually settled with the idea that there would be three types of thing in the system:
- Properties
- For example, 'light' or 'volume'. These are values that can be got and set.
- Events
- For example, 'motion detected' or 'washing finished'. These are events that can be triggered by real-world or software events.
- Actions
- For example, 'close door', 'pause' or 'is washing machine in use'. These are a bit like function calls and can optionally take arguments and return values.
Unfortunately, this model doesn't really fit into a real file system and so the idea of using a FUSE file system to literally 'mount' our house was quickly abandoned. Instead we settled on producing a command-line utility and API for accessing the system.
Since the system was going to be house-wide it was going to need to run across a network. After looking around for libraries and protocols we could use to implement our system we eventually decided to write our own. Event-based systems existed but they were either far too enterprisey or too complicated. We also looked at using a standard RPC library but these once again proved overly complicated and lacked a reasonable way dealing with events.
We decided on a centralised architecture with a single server and multiple clients. In our system the server would be pretty 'dumb' with all the application logic going on in the clients. The clients tell the server what nodes in the tree they contained and set/get properties, call actions or listen for events via the server that were created by other clients.
For example, we could have a client connected to light switches in the house, a client which monitored motion sensors and another client which listened for motion events from the second client and turned lights attached to the first on and off as needed. We could also run clients on our own computers to allow media players to be controlled over SHET.
Speed wasn't an issue seeing as this would be running on a LAN and so we focused our efforts on making the protocol simple human readable. After wrangling with some RPC frameworks and seeing how much hassle data types were, we decided we didn't want to deal with type-safety and so using JSON to encapsulate values in the system seemed like a good idea. From there it was obvious to use JSON to encode messages in the protocol too. After a late night on IRC Tom and Jonathan settled on what became known as the SHET protocol.
Unfortunately, as you might have guessed, the name is actually a backronym. From the IRC logs of SHET's conception:
(23:55:38) Jonathan: name for the protocol ? (23:55:47) tomn: lol, no idea. (23:56:00) Jonathan: karls: ideas? (23:56:22) tomn: just string some buzwords together and acronym the hell out of it :p (23:57:10) Jonathan: :D (23:57:30) Jonathan: take a list of rude or amusing words and swap the vowels and then acronym the hell out of that
With the protocol designed, implementation was next on the list. Coursework deadlines loomed and so there was no time like the present and Tom set about writing the SHET Python API and SHET server using the Twisted framework. Twisted describes itself as "an event-driven networking engine written in Python" and provides a really nice API for implementing network protocols.
(TODO: Example client here)
As well as a Python API, a command-line utility was also made (complete with bash-completion). It allowed easy direct interaction with SHET and its servers. For example, you could browse through the tree with tab completion:
$ shet /jonathan/<tab> /jonathan/arduino/ /jonathan/irc/ /jonathan/sound/ /jonathan/desktop/ /jonathan/mpd/ /jonathan/tts/ /jonathan/email /jonathan/sms
Call actions (with arguments) and see their returned values:
$ shet /matt/mpd/toggle 0 $ shet /tom/sms "Let me know when you get in" null
Get and set properties:
$ shet /jonathan/sound/speakers/volume 100 $ shet /jonathan/sound/speakers/volume 21 null $ shet /jonathan/sound/speakers/volume 21
Watch events being raised:
$ shet /lounge/panel/pressed [6] [4] [1] ...
Of course, this interface meant that we could actually write shell scripts to control our house. For example, alarm clocks which could turn on lights and music could be created in seconds using a cron job.
After a while we got fed up of the command-line client being relatively slow (due to the overhead of starting Python). This (and further coursework deadlines) was all the motivation it took for Tom to write a C library for SHET and a command-line SHET client written in C.
The madness didn't stop here either as a JavaScript library appeared allowing us to build web interfaces trivially for any device. The library is built on Node.js and Socket.IO and is just as feature complete as the C and Python versions.

SHETSource (Controlling Real-World Things)
Right from the start, our aim was to control real things in our house like the lights. This meant having these things somehow connected to SHET. The answer we came up with was to use Arduinos thanks to their ease of use and off-the-shelf availability. They would allow us to run simple programs which controlled motors, switches, sensors, lights and anything else we could wire up around the house.
Of course, connecting these Arduinos to SHET posed a problem. Our first thought was that we might use an Ethernet shield and connect them all to our computer network. Unfortunately, the shields would be too expensive and since there would only be one network socket in each room, we'd have to buy lots of Ethernet switches too. We'd also need to power the Arduinos and their attached peripherals. Power-over-Ethernet was deemed too complicated and once again, too expensive.
After dismissing various bad ideas involving long USB cables and repeaters, Tom remembered that 10/100 Ethernet only uses four of the eight wires in a standard CAT-5 cable. As we didn't plan on using gigabit networking in our house, it meant we'd have four wires running from somewhere central in the house to every other room.
In order to use these unused wires, we had to make adapters which
split off the four Ethernet wires and the four spare wires at each end.
This meant re-writing the wall-sockets in each room and making adapters
for the cables in our
comms electrical meter cupboard where
they were connected to the switch.
You might be wondering how common it is to find a full CAT-5 installation in a cheap student house and the answer is: not at all. When our very keen landlord offered to do "anything we could think of" while renovating the property we were pretty sceptical. A joking remark about fitting CAT-5 (and a plasma TV) were met with "sure" and we left not really thinking anything would happen. When he later contacted us to find out where we'd like the wall sockets we were pretty surprised.
So, with four wires available to us, this meant two for power and two for data (to keep things simple). Jonathan started experimenting with I2C, a simple data bus protocol, to connect the Arduinos together. There would be a 'master' Arduino connected to our server which would act as the interface between all the other Arduinos and SHET.
Despite our enthusiasm, we realised I2C really wasn't designed for long wires. After lots of head-scratching, continuity testing and fiddling with I2C settings Tom eventually found an I2C booster that might be the answer to our problems. A few days later and we wired up our shiny boosters and...it still didn't work.
At this point, we scrapped our plan of using I2C and instead started building a simple software serial library with basic flow control capabilities. To keep things simple, we decided to abandon the idea of using a bus and instead would connect the two data wires of each Arduino around the house directly into the otherwise unused pins of the master Arduino. The master would then route data to and from our server over USB.
Once again we connected everything up and...it worked! Now all we needed was a way of exposing all this to SHET.
After seeing the fairly dreadful performance of our serial link, we ditched any ideas about using the regular SHET protocol. Instead we considered a simple protocol which basically forwarded control of the IO pins back to our server. This idea seemed like an extremely wasteful use of Arduinos and so Jonathan set about designing a simple protocol which complemented SHET.
The idea was that each Arduino should be able to create events, properties and actions within SHET. These could be, for example, motion sensors, lights and buzzers. To keep things simple, it was decided that Arduinos would not be able to access other events, properties and actions within SHET, instead SHET clients would be written to fill the gap. This also forced us to keep our "application logic" off the Arduinos which would save lots of time constantly reprogramming them.
From this idea, SHETSource was born making it trivial to connect real-world things to SHET. Take a look at the following Arduino sketch which makes the internal LED controllable over SHET:
#include <pins.h> #include <comms.h> #include <SHETSource.h> /* Connect to SHETSource via pins 2 and 3. */ DirectPins pins = DirectPins(2,3); Comms comms = Comms(&pins); /* The SHETSource client. Set that by default, nodes are created in the * /arduino/ subdirectory in SHET. */ SHETSource::Client client = SHETSource::Client(&comms, "arduino"); /* Get the state of the LED */ int get_led(void) { return digitalRead(13); } /* Set the state of the LED */ void get_led(int state) { digitalWrite(13, state); } void setup() { client.Init(); /* Use the built-in LED */ pinMode(13, OUTPUT); /* Register a property for the LED in /arduino/led. */ client.AddProperty("led", set_led, get_led); } void loop() { /* Execute one iteration of the SHETSource mainloop. */ client.DoSHET(); }
For an embarrassingly long time, SHETSource sat in a state of being usable but somewhat unreliable due to a simple timing bug. With this fixed, everything ran smoothly until one day our electrical simplifications came back to bite us. After sitting down in the living room one day, Jonathan noticed various Arduinos were no longer responding. After chalking this up to yet another timing issue in the system, the problem sat ignored until later that evening when the affected Arduinos were found nice and toasty in their sockets. The cable carrying data and power to the Arduino in the lounge appeared to have shorted fairly badly taking out several Arduinos in the house. A binary search of the offending length of wire revealed a very poorly piece of cable trapped under a leg of the sofa.
After replacing the cable and AVRs, we still didn't feel motivated to put any proper electrical protection in place and instead carefully blu-tacked the cable out of the reach of the evil chair leg. (Thus solving the problem once and for all!)
TODO: Talk about later direct-USB and Bluetooth interfaces to Arduinos.
Let There Be Light (Control)!
One of the major things we wanted our system to do was to control lights around the house. Unfortunately, a sensible respect for high-voltages, our land-lord's property and our own wallets meant we weren't going to be able to do anything especially fancy. After being inspired by the most useless machine, Jonathan grabbed a servo motor, some trusty blu-tack and hacked the lights in his halls bedroom.
With this idea and a number of cheap (and apparently sand-lubricated) servos off ebay we gained control of almost all the lights around the house. Once again our shoddy electronics (and ridiculously long power wires) started causing us problems. When the servos were moved, they would stutter and nearby Arduinos would brown out. The solution was simply to add a nice meaty capacitor across the regulator that powered it.
Unfortunately, a couple of rooms (perhaps ironically, those of SHET's principle developers, Tom and Jonathan) were fitted with dimmer switches which weren't especially forthcoming to servo control. Many an idea involving 3D-printed gears and dismantled CD-ROM drives was conceived but still the lights remained rebelliously uncontrolled.
While Tom was browsing around Clas Ohlson he discovered some cheap, remote controlled wall sockets which looked like an ideal candidate for hacking. By hacking the remote, we would be able to control mains-voltage devices without touching anything high-voltage.
This store, incidentally, is the supplier of a bewildering selection of goods notably including what we've dubbed 'SHAT-5', the generic dual-twisted-pair cable SHETSource lives in after it leaves the safety of the CAT-5 wall sockets.
With a selection of individually controllable standalone lamps lighting Tom's room, the hack was declared a success. Such was their effectiveness that when a light fitting broke in our hallway, Christmas lights and a wireless socket were rigged up (in June) and set up in SHET as the hallway lights and normal (if a prematurely festive) service was resumed.
Unfortunately, Jonathan was still without controllable lighting. Tempted by Tom's discovery of relatively inexpensive LED strips, Jonathan ordered 5m of RGB LED strip with the hope of using it to light his room. Tom more sensibly opted for 5m of warm-white LEDs and we both waited as they made their way from China to our revision-worn hands.
Somewhat unsurprisingly, the RGB LED strip produced a cold, blue-white light which wasn't going to be ideal for standard room lighting. It did, however, prove pretty awesome when combined with Mattuliser, a music visualisation library Matt wrote.
What was surprising was just how bright and how pleasant the warm-white LEDs Tom bought were. Lengths were hung around his room and connected to his Arduino via some questionable ebay MOSFETs (with equally questionable heat sinks). The result was dimmable and very pleasant lighting and a further order of the same LED strip from Jonathan. A little while later and Jonathan's room too was bathed in glorious PWM'd light.
Who needs light switches anyway? (Automatic Lighting)
What use are computer controlled lighting without some sort of motion detection to automate turning lights on and off? The idea of hacking the burglar alarm's PIR?s (motion detectors) came up early on. Unfortunately we didn't want to annoy our landlord (or neighbours) by tampering with it directly and so settled with attaching an LDR (light sensor) over the flashing LED (so that's why they flash...).
Not every room had a PIR and so we turned again to ebay and bought some cheap PIR modules. When fed 5v, these modules simply provide a pulse easily read by an Arduino whenever they detect movement. Easy!
With controllable lights and motion sensors all over the house all we needed to do was quickly hack together a SHET client to "just do the obvious thing". Unfortunately, as with any human interface problem, it turned out this was going to be harder than we thought...
TODO: Story of the lighting server and the problem of trivially describing the "sensible" time to turn lights on and off.
The Button Panel (of Dreams and Nightmares)
Despite the fact that our system allowed us to automate many things, others would always require direct human interaction. One place in particular, our lounge & kitchen, required particular attention as there were plenty of opportunities for SHET control.
We search around the piles of miscellaneous buttons, dials and LEDs we had lying around and came up with an idea for a control panel. As there are five of us in the house, we wanted to have at least one button per person. For example, you could press a button and your playlist would be copied onto the computer in the lounge. In order to make the most of this small number of buttons, we wanted to allow chording (pressing more than one key at once) and long-pressing to squeeze more functions into the panel.
Despite the existence of theoretically up to 30 different actions, the system would be very arbitrary and unpleasant to use or learn. To make things clearer, we decided we'd add another button to allow multiple modes to be selected. For example, in a 'music' mode, you can easily control playback by pressing one of the five buttons or grab your playlist by pressing and holding 'your' button (as dictated by the alphabetical ordering of our names). In a 'washing machine reminder' mode, you could press your button to book a reminder and press-and-hold to clear it. To indicate what mode the panel was in, we added an RGB LED and each mode was allocated a colour.
Pressing the mode button would cycle through the different modes (giving a pleasing demo of the RGB LED...) and pressing the mode button along with one of the five main buttons a specific mode could be selected. This meant that we'd have only 5 modes and that wouldn't allow us to also have our own personalised modes. As a result, we added a second mode button which gave us each our own personal modes.
With all this talk of modes Matt, our resident Emacs user, was getting uncomfortable. We're also computer scientists and so the thought of being limited to only 300 actions seemed limiting. To improve the situation, a modifier key was added named the 'middle-switch'.
Surprisingly, this system proved reasonably easy to use, especially given that in essence it was a box with 8 anonymous buttons and an LED. Now that we had our system, we needed a way to bind key presses to things in SHET. Faced with this task, Jonathan set about creating panel-o-matic. It consists of a custom language for specifying button behaviours and a SHET client which takes button-press and mode-change events from the panel and sets properties or calls actions as appropriate. Here's an example of a configuration file.
MUSIC { // In music mode, pressing a button will trigger one of the following actions 0 => /lounge/mpd/prev; 1 => /lounge/mpd/next; 2 => /lounge/mpd/toggle; 3 => /lounge/amplifier/vol_dec 20; 4 => /lounge/amplifier/vol_inc 20; // Pressing the 'middle-switch' (modifier) and button 0 enables random mode ^0 => /lounge/mpd/random 1; // Pressing and holding with the middle-switch turns random mode off. _^0 => /lounge/mpd/random 0; // The _ indicates "holding down" a key, and the special "any(...)" syntax // allows any one of the listed keys to be pressed and the associated string // be passed to the action as an argument. _any(0 : "james" ,1 : "jonathan" ,2 : "karl" ,3 : "matt" ,4 : "tom") => /lounge/mpd/copy_playlist_from; }
With the panel finished, it was time to put it to work. The first and most obvious thing to do was allow control of MPD (the media player on our lounge computer). Since we already had an MPD SHET client, this simply required adding all the actions we wanted to the button panel configuration and took all of 5 minutes!
With a sensor on the washing machine and the SHET email-sending client, we had been setting up reminders by using the 'bind' client to set up a one-off binding that would cause the 'washing finished' notification to call the 'send email' action for the appropriate person. To allow bookings to be made and cancelled from the button panel, all we needed for each person was a panel-o-matic configuration along the lines of:
// Booking reminders with a press 0 => /bind/once /lounge/washing_machine/finished /james/email; // Cancelling reminders with a press-and-hold _0 => /bind/rm /lounge/washing_machine/finished /james/email;
Once again, a really useful feature implemented with a minimum of effort. As a finishing touch, we bound the "washing starting" event to change the panel to the reminder booking mode automatically.
Another feature we wanted was to be able to browse our house recipe website from the panel. Again, all we needed was to use the panel to trigger calls to the 'keybind' client on the lounge computer. As you can see from the video, the panel makes a surprisingly usable interface for browsing around from the other side of the kitchen.
We've also got a mode for interacting with IRC enabling requests for washing up and letting people know when dinner is ready.
We have one other miscellaneous mode which contains useful commands for interacting with the computer (such as close window). It also has a button which 'powers down' the room turning off music, screens and lights and turning on a light in the hallway.
The individual user modes have been fairly sparsely used in practice. They do however serve a few useful services. For example in Jonathan's mode there is a button which turns off his lights and music while copying his playlist into the lounge media player and launching the recipe browser. It also serves some less useful (but obviously more important services), for example, Matt's mode is an in-joke and meme sound-board.

Getting Started (Downloads & Docs)
We think SHET is a really cool base for hackable home automation systems. If you're interested in trying it out yourself then here's a few links you might want to get started. SHET and SHETSource are currently moderately well documented and fairly stable so you should be able to get going without too much difficulty.
As you might imagine, a lot of the clients we've written are very specific to our house's setup and quickly hacked together to scratch an itch. They also come with an embarrassing quantity of documentation but hopefully should be occasionally useful.

Tutorial: Building Redux in TypeScript with Angular
Reading Time: 29 minutes
tl;dr – In this post we’ll be looking at a data-architecture pattern called Redux. In this post we’re going to discuss:
- the ideas behind Redux,
- build our own mini version of the Redux Store and
- hook it up to Angular.
You can get the completed code here
You can try the demo here
For many Angular projects we can manage state in a fairly direct way: We tend to grab data from services and render them in components, passing values down the component tree along the way.
Managing our apps in this way works fine for smaller apps, but as our apps grow, having multiple components manage different parts of the state becomes cumbersome. For instance, passing all of our values down our component tree suffers from the following downsides:
Intermediate property passing – In order to get state to any component we have to pass the values down through
inputs. This means we have many intermediate components passing state that it isn’t directly using or concerned about
Inflexible refactoring – Because we’re passing
inputs down through the component tree, we’re introducing a coupling between parent and child components that often isn’t necessary. This makes it more difficult to put a child component somewhere else in the hierarchy because we have to change all of the new parents to pass the state
State tree and DOM tree don’t match – The “shape” of our state often doesn’t match the “shape” of our view/component hierarchy. By passing all data through the component tree via
props we run into difficulties when we need to reference data in a far branch of the tree
State throughout our app – If we manage state via components, it’s difficult to get a snapshot of the total state of our app. This can make it hard to know which component “owns” a particular bit of data, and which components are concerned about changes
Pulling data out of our components and into services helps a lot. At least if services are the “owners” of our data, we have a better idea of where to put things. But this opens a new question: what are the best practices for “service-owned” data? Are there any patterns we can follow? In fact, there are.
In this post, we’re going to discuss a data-architecture pattern called Redux which was designed to help with these issues. We’ll implement our own version of Redux which will store all of our state in a single place. This idea of holding all of our application’s state in one place might sound a little crazy, but the results are surprisingly delightful.
Redux
If you haven’t heard of Redux yet you can read a bit about it on the official website. Web application data architecture is evolving and the traditional ways of structuring data aren’t quite adequate for large web apps. Redux has been extremely popular because it’s both powerful and easy to understand.
Data architecture can be a complex topic and so Redux’s best feature is probably its simplicity. If you strip Redux down to the essential core, Redux is fewer than 100 lines of code.
We can build rich, easy to understand, web apps by using Redux as the backbone of our application. But first, let’s walk through how to write a minimal Redux and later we’ll work out patterns that emerge as we work out these ideas in a larger app.
There are several attempts to use Redux or create a Redux-inspired system that works with Angular. Two notable examples are:
ngrxis a Redux-inspired architecture that is heavily observables-based.
angular2-reduxuses Redux itself as a dependency, and adds some Angular helpers (dependency-injection, observable wrappers).
Here we’re not going to use either. Instead, we’re going to use Redux directly in order to show the concepts without introducing a new dependency. That said, both of these libraries may be helpful to you when writing your apps.
Redux: Key Ideas
The key ideas of Redux are this:
- All of your application’s data is in a single data structure called the state which is held in the store
- Your app reads the state from this store
- This store is never mutated directly
- User interaction (and other code) fires actions which describe what happened
- A new state is created by combining he old state and the action by a function called the reducer.
If the above bullet list isn’t clear yet, don’t worry about it – putting these ideas into practice is the goal of the rest of this post.

Core Redux Ideas
What’s a reducer?
Let’s talk about the reducer first. Here’s the idea of a reducer: it takes the old state and an action and returns a new state.
A reducer must be a pure function. That is:
- It must not mutate the current state directly
- It must not use any data outside of its arguments
Put another way, a pure function will always return the same value, given the same set of arguments. And a pure function won’t call any functions which have an effect on the outside world, e.g. no database calls, no HTTP calls, and no mutating outside data structures.
Reducers should always treat the current state as read-only. A reducer does not change the state instead, it returns a new state. (Often this new state will start with a copy of old state, but let’s not get ahead of ourselves.)
Let’s define our very first reducer. Remember, there are three things involved:
- An
Action, which defines what to do (with optional arguments)
- The
state, which stores all of the data in our application
- The
Reducerwhich takes the
stateand the
Actionand returns a new state.
Defining
Action and
Reducer Interfaces
Since we’re using TypeScript we want to make sure this whole process is typed, so let’s setup an interface for our
Action and our
Reducer:
The
Action Interface
Our
Action interface looks like this:
interface Action { type: string; payload?: any; }
Notice that our
Action has two fields:
typeand
payload
The
type will be an identifying string that describes the action like
INCREMENT or
ADD_USER. The
payload can be an object of any kind. The
? on
payload? means that this field is optional.
The
Reducer Interface
Our
Reducer interface looks like this:
interface Reducer<T> { (state: T, action: Action): T; }
Our
Reducer is using a feature of TypeScript called generics. In this case type
T is the type of the
state. Notice that we’re saying that a valid
Reducer has a function which takes a
state (of type
T) and an
action and returns a new
state (also of type
T).
Creating Our First
Reducer
The simplest possible reducer returns the state itself. (You might call this the identity reducer because it applies the identity function on the state. This is the default case for all reducers, as we will soon see).
let reducer: Reducer<number> = (state: number, action: Action) => { return state; };
Notice that this
Reducer makes the generic type concrete to
number by the syntax
Reducer<number>. We’ll define more sophisticated states beyond a single number soon.
We’re not using the
Action yet, but let’s try this
Reducer just the same.
Running the examples in this post
You can find the code for this post on Github.
In this first section, these examples are run outside of the browser and run by node.js. Because we’re using TypeScript in these examples, you should run them using the commandline tool
ts-node, (instead of
nodedirectly).
You can install
ts-nodeby running:
npm install -g ts-node
Or by doing an
npm installin the
angular2-redux-chatdirectory and then calling
./node_modules/.bin/ts-nodet
For instance, to run the example above you might type (not including the
$):
$ cd angular2-redux-chat/minimal/tutorial $ npm install $ ./node_modules/.bin/ts-nodet 01-identity-reducer.ts
Use this same procedure for the rest of the code in this post until we instruct you to switch to your browser.
Running Our First
Reducer
Let’s put it all together and run this reducer:
interface Action { type: string; payload?: any; } interface Reducer<T> { (state: T, action: Action): T; } let reducer: Reducer<number> = (state: number, action: Action) => { return state; }; console.log( reducer(0, null) ); // -> 0
And run it:
$ cd code/redux/redux-chat/tutorial $ ./node_modules/.bin/ts-node 01-identity-reducer.ts 0
It seems almost silly to have that as a code example, but it teaches us our first principle of reducers:
By default, reducers return the original state.
In this case, we passed a state of the number
0 and a
null action. The result from this reducer is the state
0.
But let’s do something more interesting and make our state change.
Adjusting the Counter With actions
Eventually our state is going to be much more sophisticated than a single number. We’re going to be holding the all of the data for our app in the
state, so we’ll need better data structure for the state eventually.
That said, using a single number for the state lets us focus on other issues for now. So let’s continue with the idea that our
state is simply a single number that is storing a counter.
Let’s say we want to be able to change the
state number. Remember that in Redux we do not modify the state. Instead, we create actions which instruct the reducer on how to generate a new state.
Let’s create an
Action to change our counter. Remember that the only required property is a
type. We might define our first action like this:
let incrementAction: Action = { type: 'INCREMENT' }
We should also create a second action that instructs our reducer to make the counter smaller with:
let decrementAction: Action = { type: 'DECREMENT' }
Now that we have these actions, let’s try using them in our reducer:
let reducer: Reducer<number> = (state: number, action: Action) => { if (action.type === 'INCREMENT') { return state + 1; } if (action.type === 'DECREMENT') { return state - 1; } return state; };
And now we can try out the whole reducer:
let incrementAction: Action = { type: 'INCREMENT' }; console.log( reducer(0, incrementAction )); // -> 1 console.log( reducer(1, incrementAction )); // -> 2 let decrementAction: Action = { type: 'DECREMENT' }; console.log( reducer(100, decrementAction )); // -> 99
Neat! Now the new value of the state is returned according to which action we pass into the reducer.
Reducer
switch
Instead of having so many
if statements, the common practice is to convert the reducer body to a
switch statement:
let reducer: Reducer<number> = (state: number, action: Action) => { switch (action.type) { case 'INCREMENT': return state + 1; case 'DECREMENT': return state - 1; default: return state; // <-- dont forget! } }; let incrementAction: Action = { type: 'INCREMENT' }; console.log(reducer(0, incrementAction)); // -> 1 console.log(reducer(1, incrementAction)); // -> 2 let decrementAction: Action = { type: 'DECREMENT' }; console.log(reducer(100, decrementAction)); // -> 99 // any other action just returns the input state let unknownAction: Action = { type: 'UNKNOWN' }; console.log(reducer(100, unknownAction)); // -> 100
Notice that the
default case of the
switch returns the original
state. This ensures that if an unknown action is passed in, there’s no error and we get the original
state unchanged.
Q: Wait, all of my application state is in one giant
switchstatement?
A: Yes and no.
If this is your first exposure to Redux reducers it might feel a little weird to have all of your application state changes be the result of a giant
switch. There are two things you should know:
- Having your state changes centralized in one place can help a ton in maintaining your program, particularly because it’s easy to track down where the changes are happening when they’re all together. (Furthermore, you can easily locate what state changes as the result of any action because you can search your code for the token specified for that action’s
type)
- You can (and often do) break your reducers down into several sub-reducers which each manage a different branch of the state tree. We’ll talk about this later.
Action “Arguments”
In the last example our actions contained only a
type which told our reducer either to increment or decrement the state.
But often changes in our app can’t be described by a single value – instead we need parameters to describe the change. This is why we have the
payload field in our
Action.
In this counter example, say we wanted to add
9 to the counter. One way to do this would be to send 9
INCREMENT actions, but that wouldn’t be very efficient, especially if we wanted to add, say, 9000.
Instead, let’s add a
PLUS action that will use the
payload parameter to send a number which specifies how much we want to add to the counter. Defining this action is easy enough:
let plusSevenAction = { type: 'PLUS', payload: 7 };
Next, to support this action, we add a new
case to our reducer that will handle a
'PLUS' action:
let reducer: Reducer<number> = (state: number, action: Action) => { switch (action.type) { case 'INCREMENT': return state + 1; case 'DECREMENT': return state - 1; case 'PLUS': return state + action.payload; default: return state; } };
PLUS will add whatever number is in the
action.payload to the
state. We can try it out:
console.log( reducer(3, { type: 'PLUS', payload: 7}) ); // -> 10 console.log( reducer(3, { type: 'PLUS', payload: 9000}) ); // -> 9003 console.log( reducer(3, { type: 'PLUS', payload: -2}) ); // -> 1
In the first line we take the state
3 and
PLUS a payload of
7, which results in
10. Neat! However, notice that while we’re passing in a
state, it doesn’t really ever change. That is, we’re not storing the result of our reducer’s changes and reusing it for future actions.
Storing Our State
Our reducers are pure functions, and do not change the world around them. The problem is, in our app, things do change. Specifically, our state changes and we need to keep the new state somewhere.
In Redux, we keep our state in the store. The store has the responsibility of running the reducer and then keeping the new state. Let’s take a look at a minimal store:
class Store<T> { private _state: T; constructor( private reducer: Reducer<T>, initialState: T ) { this._state = initialState; } getState(): T { return this._state; } dispatch(action: Action): void { this._state = this.reducer(this._state, action); } }
Notice that our
Store is generically typed – we specify the type of the state with generic type
T. We store the state in the private variable
_state.
We also give our
Store a
Reducer, which is also typed to operate on
T, the state type this is because each store is tied to a specific reducer. We store the
Reducer in the private variable
reducer.
In Redux, we generally have 1 store and 1 top-level reducer per application.
Let’s take a closer look at each method of our
State:
- In our
constructorwe set the
_stateto the initial state.
getState()simply returns the current
_state
dispatchtakes an action, sends it to the reducer and then updates the value of
_statewith the return value
Notice that
dispatch doesn’t return anything. It’s only updating the store’s state (once the result returns). This is an important principle of Redux: dispatching actions is a “fire-and-forget” maneuver. Dispatching actions is not a direct manipulation of the state, and it doesn’t return the new state.
When we dispatch actions, we’re sending off a notification of what happened. If we want to know what the current state of the system is, we have to check the state of the store.
Using the Store
Let’s try using our store:
// create a new store let store = new Store<number>(reducer, 0); console.log(store.getState()); // -> 0 store.dispatch({ type: 'INCREMENT' }); console.log(store.getState()); // -> 1 store.dispatch({ type: 'INCREMENT' }); console.log(store.getState()); // -> 2 store.dispatch({ type: 'DECREMENT' }); console.log(store.getState()); // -> 1
We start by creating a new
Store and we save this in
store, which we can use to get the current state and dispatch actions.
The state is set to
0 initially, and then we
INCREMENT twice and
DECREMENT once and our final state is
1.
Being Notified with
subscribe
It’s great that our
Store keeps track of what changed, but in the above example we have to ask for the state changes with
store.getState(). It would be nice for us to know immediately when a new action was dispatched so that we could respond. To do this we can implement the Observer pattern – that is, we’ll register a callback function that will subscribe to all changes.
Here’s how we want it to work:
- We will register a listener function using
subscribe
- When
dispatchis called, we will iterate over all listeners and call them, which is the notification that the state has changed.
Registering Listeners
Our listener callbacks are a going to be a function that takes no arguments. Let’s define an interface that makes it easy to describe this:
interface ListenerCallback { (): void; }
After we subscribe a listener, we might want to unsubscribe as well, so lets define the interface for an unsubscribe function as well:
interface UnsubscribeCallback { (): void; }
Not much going on here – it’s another function that takes no arguments and has no return value. But by defining these types it makes our code clearer to read.
Our store is going to keep a list of
ListenerCallbacks let’s add that to our
Store:
class Store<T> { private _state: T; private _listeners: ListenerCallback[] = [];
Now we want to be able to add to that list of
_listeners with a
subscribe function:
subscribe(listener: ListenerCallback): UnsubscribeCallback { this._listeners.push(listener); return () => { // returns an "unsubscribe" function this._listeners = this._listeners.filter(l => l !== listener); }; }
subscribe accepts a
ListenerCallback (i.e. a function with no arguments and no return value) and returns an
UnsubscribeCallback (the same signature). Adding the new listener is easy: we
push it on to the
_listeners array.
The return value is a function which will update the list of
_listeners to be the list of
_listeners without the
listener we just added. That is, it returns the
UnsubscribeCallback that we can use to remove this listener from the list.
Notifying Our Listeners
Whenever our state changes, we want to call these listener functions. What this means is, whenever we
dispatch a new action, whenever the state changes, we want to call all of the listeners:
dispatch(action: Action): void { this._state = this.reducer(this._state, action); this._listeners.forEach((listener: ListenerCallback) => listener()); }
The Complete Store
We’ll try this out below, but before we do that, here’s the complete code listing for our new
Store:
class Store<T> { private _state: T; private _listeners: ListenerCallback[] = []; constructor( private reducer: Reducer<T>, initialState: T ) { this._state = initialState; } getState(): T { return this._state; } dispatch(action: Action): void { this._state = this.reducer(this._state, action); this._listeners.forEach((listener: ListenerCallback) => listener()); } subscribe(listener: ListenerCallback): UnsubscribeCallback { this._listeners.push(listener); return () => { // returns an "unsubscribe" function this._listeners = this._listeners.filter(l => l !== listener); }; } }
Trying Out
subscribe
Now that we can
let store = new Store<number>(reducer, 0); console.log(store.getState()); // -> 0 // subscribe let unsubscribe = store.subscribe(() => { console.log('subscribed: ', store.getState()); }); store.dispatch({ type: 'INCREMENT' }); // -> subscribed: 1 store.dispatch({ type: 'INCREMENT' }); // -> subscribed: 2 unsubscribe(); store.dispatch({ type: 'DECREMENT' }); // (nothing logged) // decrement happened, even though we weren't listening for it console.log(store.getState()); // -> 1
Above we subscribe to our store and in the callback function we’ll log
subscribed: and then the current store state.
Notice that the listener function is not given the current state as an argument. This might seem like an odd choice, but because there are some nuances to deal with, it’s easier to think of the notification of state changed as separate from the current state. Without digging too much into the weeds, you can read more about this choice here, here, and here.
We store the
unsubscribe callback and then notice that after we call
unsubscribe() our log message isn’t called. We can still dispatch actions, we just won’t see the results until we ask the store for them.
If you’re the type of person who likes RxJS and Observables, you might notice that implementing our own subscription listeners could also be implemented using RxJS. You could rewrite our
Storeto use Observables instead of our own subscriptions.
In fact, we’ve already done this for you and you can find the sample code in the file
code/redux/redux-chat/tutorial/06b-rx-store.ts.
Using RxJS for the
Storeis an interesting and powerful pattern if you’re willing to us RxJS for the backbone of our application data.
Here we’re not going to use Observables very heavily, particularly because we want to discuss Redux itself and how to think about data architecture with a single state tree. Redux itself is powerful enough to use in our applications without Observables.
Once you get the concepts of using “straight” Redux, adding in Observables isn’t difficult (if you already understand RxJS, that is). For now, we’re going to use “straight” Redux and we’ll give you some guidance on some Observable-based Redux-wrappers at the end.
The Core of Redux
The above store is the essential core of Redux. Our reducer takes the current state and action and returns a new state, which is held by the store.
Here’s our minimal TypeScript Redux stores in one image (click for larger version):
There are obviously many more things that we need to add to build a large, production web app. However, all of the new ideas that we’ll cover are patterns that flow from building on this simple idea of an immutable, central store of state. If you understand the ideas presented above, you would be likely to invent many of the patterns (and libraries) you find in more advanced Redux apps.
There’s still a lot for us to cover about day-to-day use of redux though. For instance, we need to know:
- How to carefully handle more complex data structures in our state
- How to be notified when our state changes without having to poll the state (with subscriptions)
- How to intercept our dispatch for debugging (a.k.a. middleware)
- How to compute derived values (with selectors)
- How to split up large reducers into more manageable, smaller ones (and recombine them)
- How to deal with asynchronous data
While we’ll explain several of these in this post, if you want to go more in-depth with a Redux example with Angular two, checkout the Intermediate Redux chapter in ng-book 4
Let’s first deal with handling more complex data structures in our state. To do that, we’re going to need an example that’s more interesting than a counter. Let’s start building a chat app where users can send each other messages.
A Messaging App
In our messaging app, as in all Redux apps, there are three main parts to the data model:
- The state
- The actions
- The reducer
Messaging App
state
The
state in our counter app was a single number. However in our messaging app, the
state is going to be an object.
This state object will have a single property,
messages.
messages will be an array of strings, with each string representing an individual message in the application. For example:
// an example `state` value { messages: [ 'here is message one', 'here is message two' ] }
We can define the type for the app’s state like this:
interface AppState { messages: string[]; }
Messaging App
actions
Our app will process two actions:
ADD_MESSAGE and
DELETE_MESSAGE.
The
ADD_MESSAGE action object will always have the property
message, the message to be added to the state. The
ADD_MESSAGE action object has this shape:
{ type: 'ADD_MESSAGE', message: 'Whatever message we want here' }
The
DELETE_MESSAGE action object will delete a specified message from the state. A challenge here is that we have to be able to specify which message we want to delete.
If our messages were objects, we could assign each message an
id property when it is created. However, to simplify this example, our messages are just simple strings, so we’ll have to get a handle to the message another way. The easiest way for now is to just use the index of the message in the array (as a proxy for the ID).
With that in mind, the
DELETE_MESSAGE action object has this shape:
{ type: 'DELETE_MESSAGE', index: 2 // <- or whatever index is appropriate }
We can define the types for these actions by using the
interface ... extends syntax in TypeScript:
interface AddMessageAction extends Action { message: string; } interface DeleteMessageAction extends Action { index: number; }
In this way our
AddMessageAction is able to specify a
message and the
DeleteMessageAction will specify an
index.
Messaging App
reducer
Remember that our reducer needs to handle two actions:
ADD_MESSAGE and
DELETE_MESSAGE. Let’s talk about these individually.
Reducing
ADD_MESSAGE
let reducer: Reducer<AppState> = (state: AppState, action: Action): AppState => { switch (action.type) { case 'ADD_MESSAGE': return { messages: state.messages.concat( (<AddMessageAction>action).message ), };
We start by switching on the
action.type and handling the
ADD_MESSAGE case.
TypeScript objects already have a type, so why are we adding a
typefield?
There are many different ways we might choose to handle this sort of “polymorphic dispatch”. Keeping a string in a
typefield (where
typemeans “action-type”) is a straightforward, portable way we can use to distinguish different types of actions and handle them in one reducer. In part, it means that you don’t have to create a new
interfacefor every action.
That said, it would be more satisfying to be able to use reflection to switch on the concrete type. While this might become possible with more advanced type guards, this isn’t currently possible in today’s TypeScript.
Broadly speaking, types are a compile-time construct and this code is compiled down to JavaScript and we can lose some of the typing metadata.
That said, if switching on a
typefield bothers you and you’d like to use language features directly, you could use the decoration reflection metadata. For now, a simple
typefield will suffice.
Adding an Item Without Mutation
When we handle an
ADD_MESSAGE action, we need to add the given message to the state. As will all reducer handlers, we need to return a new state. Remember that our reducers must be pure and not mutate the old state.
What would be the problem with the following code?
case 'ADD_MESSAGE': state.messages.push( action.message ); return { messages: messages }; // ...
The problem is that this code mutates the
state.messages array, which changes our old state! Instead what we want to do is create a copy of the
state.messages array and add our new message to the copy.
case 'ADD_MESSAGE': return { messages: state.messages.concat( (<AddMessageAction>action).message ), };
The syntax
<AddMessageAction>actionwill cast our
actionto the more specific type. That is, notice that our reducer takes the more general type
Action, which does not have the
messagefield. If we leave off the cast, then the compiler will complain that
Actiondoes not have a field
Instead, we know that we have an
ADD_MESSAGEaction so we cast it to an
AddMessageAction. We use parenthesis to make sure the compiler knows that we want to cast
actionand not
action.message.
Remember that the reducer must return a new
AppState. When we return an object from our reducer it must match the format of the
AppState that was input. In this case we only have to keep the key
messages, but in more complicated states we have more fields to worry about.
Deleting an Item Without Mutation
Remember that when we handle the
DELETE_MESSAGE action we are passing the index of the item in the array as the faux ID. (Another common way of handling the same idea would be to pass a real item ID.) Again, because we do not want to mutate the old
messages array, we need to handle this case with care:
case 'DELETE_MESSAGE': let idx = (<DeleteMessageAction>action).index; return { messages: [ ...state.messages.slice(0, idx), ...state.messages.slice(idx + 1, state.messages.length) ]
Here we use the
slice operator twice. First we take all of the items up until the item we are removing. And we concatenate the items that come after.
There are four common non-mutating operations:
- Adding an item to an array
- Removing an item from an array
- Adding / changing a key in an object
- Removing a key from an object
The first two (array) operations we just covered. We’ll talk more about the object operations further down, but for now know that a common way to do this is to use
Object.assign. As in:
Object.assign({}, oldObject, newObject) // <-------<-------------
You can think of
Object.assignas merging objects in from the right into the object on the left.
newObjectis merged into
oldObjectwhich is merged into
{}. This way all of the fields in
oldObjectwill be kept, except for where the field exists in
newObject. Neither
oldObjectnor
newObjectwill be mutated.
Of course, handling all of this on your own takes great care and it is easy to make a mistake. This is one of the reasons many people use Immutable.js, which is a set of data structures that help enforce immutability.
Trying Out Our Actions
Now let’s try running our actions:
let store = new Store<AppState>(reducer, { messages: [] }); console.log(store.getState()); // -> { messages: [] } store.dispatch({ type: 'ADD_MESSAGE', message: 'Would you say the fringe was made of silk?' } as AddMessageAction); store.dispatch({ type: 'ADD_MESSAGE', message: 'Wouldnt have no other kind but silk' } as AddMessageAction); store.dispatch({ type: 'ADD_MESSAGE', message: 'Has it really got a team of snow white horses?' } as AddMessageAction); console.log(store.getState()); // -> // { messages: // [ 'Would you say the fringe was made of silk?', // 'Wouldnt have no other kind but silk', // 'Has it really got a team of snow white horses?' ] }
Here we start with a new store and we call
store.getState() and see that we have an empty
messages array.
Next we add three messages to our store. For each message we specify the
type as
ADD_MESSAGE and we cast each object to an
AddMessageAction.
Finally we log the new state and we can see that
messages contains all three messages.
Our three
dispatch statements are a bit ugly for two reasons:
- we manually have to specify the
typestring each time. We could use a constant, but it would be nice if we didn’t have to do this and
- we’re manually casting to an
AddMessageAction
Instead of creating these objects as an object directly we should create a function that will create these objects. This idea of writing a function to create actions is so common in Redux that the pattern has a name: Action Creators.
Action Creators
Instead of creating the
ADD_MESSAGE actions directly as objects, let’s create a function to do this for us:
class MessageActions { static addMessage(message: string): AddMessageAction { return { type: 'ADD_MESSAGE', message: message }; } static deleteMessage(index: number): DeleteMessageAction { return { type: 'DELETE_MESSAGE', index: index }; } }
Here we’ve created a class with two static methods
addMessage and
deleteMessage. They return an
AddMessageAction and a
DeleteMessageAction respectively.
You definitely don’t have to use static methods for your action creators. You could use plain functions, functions in a namespace, even instance methods on an object, etc. The key idea is to keep them organized in a way that makes them easy to use.
Now let’s use our new action creators:
let store = new Store<AppState>(reducer, { messages: [] });?' ] }
This feels much nicer!
An added benefit is that if we eventually decided to change the format of our messages, we could do it without having to update all of our
dispatch statements. For instance, say we wanted to add the time each message was created. We could add a
created_at field to
addMessage and now all
AddMessageActions will be given a
created_at field:
class MessageActions { static addMessage(message: string): AddMessageAction { return { type: 'ADD_MESSAGE', message: message, // something like this created_at: new Date() }; } // ....
Using Real Redux
Now that we’ve built our own mini-redux you might be asking, “What do I need to do to use the real Redux?” Thankfully, not very much. Let’s update our code to use the real Redux now!
If you haven’t already, you’ll want to run
npm installin the
code/redux/redux-chat/tutorialdirectory.
The first thing we need to do is import
Action,
Reducer, and
Store from the
redux package. We’re also going to import a helper method
createStore while we’re at it:
import { Action, Reducer, Store, createStore } from 'redux';
Next, instead of specifying our initial state when we create the store instead we’re going to let the reducer create the initial state. Here we’ll do this as the default argument to the reducer. This way if there is no state passed in (e.g. the first time it is called at initialization) we will use the initial state:
let initialState: AppState = { messages: [] }; let reducer: Reducer<AppState> = (state: AppState = initialState, action: Action) => {
What’s neat about this is that the rest of our reducer stays the same!
The last thing we need to do is create the store using the
createStore helper method from Redux:
let store: Store<AppState> = createStore<AppState>(reducer);
After that, everything else just works!
let store: Store<AppState> = createStore<AppState>(reducer);?' ] }
Now that we have a handle on using Redux in isolation, the next step is to hook it up to our web app. Let’s do that now.
Using Redux in Angular
In the last section we walked through the core of Redux and showed how to create reducers and use stores to manage our data in isolation. Now it’s time to level-up and integrate Redux with our Angular components.
In this section we’re going to create a minimal Angular app that contains just a counter which we can increment and decrement with a button.
By using such a small app we can focus on the integration points between Redux and Angular and then we can move on to a larger app in the next section. But first, let’s see how to build this counter app!
Here we are going to be integrating Redux directly with Angular without any helper libraries in-between. There are several open-source libraries with the goal of making this process easier, and you can find them in the references section below.
That said, it can be much easier to use those libraries once you understand what is going on underneath the hood, which is what we work through here.
Planning Our App
If you recall, the three steps to planning our Redux apps are to:
- Define the structure of our central app state
- Define actions that will change that state and
- Define a reducer that takes the old state and an action and returns a new state.
For this app, we’re just going to increment and decrement a counter. We did this in the last section, and so our actions, store, and reducer will all be very familiar.
The other thing we need to do when writing Angular apps is decide where we will create components. In this app, we’ll have a top-level
AppComponent which will have one component, the
AppComponent which contains the view we see in the screenshot.
At a high level we’re going to do the following:
- Create our
Storeand make it accessible to our whole app via dependency injection
Storeand display them in our components
- When something changes (a button is pressed) we will dispatch an action to the
Store.
Enough planning, let’s look at how this works in practice!
Setting Up Redux
Defining the Application State
Let’s take a look at our
AppState:
export interface AppState { counter: number; };
Here we are defining our core state structure as
AppState – it is an object with one key,
counter which is a
number. In the next example (the chat app) we’ll talk about how to have more sophisticated states, but for now this will be fine.
Defining the Reducers
Next lets define the reducer which will handle incrementing and decrementing the counter in the application state:
import { INCREMENT, DECREMENT } from './counter.actions'; const initialState: AppState = { counter: 0 }; // Create our reducer that will handle changes to the state export const counterReducer: Reducer<AppState> = (state: AppState = initialState, action: Action): AppState => { switch (action.type) { case INCREMENT: return Object.assign({}, state, { counter: state.counter + 1 }); case DECREMENT: return Object.assign({}, state, { counter: state.counter - 1 }); default: return state; } };
We start by importing the constants
INCREMENT and
DECREMENT, which are exported by our action creators. They’re just defined as the strings
'INCREMENT' and
'DECREMENT', but it’s nice to get the extra help from the compiler in case we make a typo. We’ll look at those action creators in a minute.
The
initialState is an
AppState which sets the counter to
0.
The
counterReducer handles two actions:
INCREMENT, which adds
1 to the current counter and
DECREMENT, which subtracts
1. Both actions use
Object.assign to ensure that we don’t mutate the old state, but instead create a new object that gets returned as the new state.
Since we’re here, let’s look at the action creators
Defining Action Creators
Our action creators are functions which return objects that define the action to be taken.
increment and
decrement below return an object that defines the appropriate
type.
import { Action, ActionCreator } from 'redux'; export const INCREMENT: string = 'INCREMENT'; export const increment: ActionCreator<Action> = () => ({ type: INCREMENT }); export const DECREMENT: string = 'DECREMENT'; export const decrement: ActionCreator<Action> = () => ({ type: DECREMENT });
Notice that our action creator functions return the type
ActionCreator<Action>.
ActionCreator is a generic class defined by Redux that we use to define functions that create actions. In this case we’re using the concrete class
Action, but we could use a more specific
Action class, such as
AddMessageAction that we defined in the last section.
Creating the Store
Now that we have our reducer and state, we could create our store like so:
let store: Store<AppState> = createStore<AppState>(counterReducer);
However, one of the awesome things about Redux is that it has a robust set of developer tools. Specifically, there is a Chrome extension that will let us monitor the state of our application and dispatch actions.
What’s really neat about the Redux Devtools is that it gives us clear insight to every action that flows through the system and it’s affect on the state.
Go ahead and install the Redux Devtools Chrome extension now!
In order to use the Devtools we have to do one thing: add it to our store.
const devtools: StoreEnhancer<AppState> = window['devToolsExtension'] ? window['devToolsExtension']() : f => f;
Not everyone who uses our app will necessarily have the Redux Devtools installed. The code above will check for
window.devToolsExtension, which is defined by Redux Devtools, and if it exists, we will use it. If it doesn’t exist, we’re just returning an identity function (
f => f) that will return whatever is passed to it.
Middleware is a term for a function that enhances the functionality of another library. The Redux Devtools is one of many possible middleware libraries for Redux. Redux supports lots of interesting middleware and it’s easy to write our own.
You can read more about Redux middleware here
In order to use this
devtools we pass it as middleware to our Redux store:
export function createAppStore(): Store<AppState> { return createStore<AppState>( reducer, compose(devtools) ); }
Now whenever we dispatch an action and change our state, we can inspect it in our browser!
Providing the Store
Now that we have the Redux core setup, let’s turn our attention to our Angular components. Let’s create our top-level app component,
AppComponent. This will be the component we use to
bootstrap Angular:
We’re going to use the
AppComponent as the root component. Remember that since this is a Redux app, we need to make our store instance accessible everywhere in our app. How should we do this? We’ll use dependency injection (DI).
When we want to make something available via DI, then we use the
providers configuration to add it to the list of
providers in our
NgModule.
When we provide something to the DI system, we specify two things:
- the token to use to refer this injectable dependency
- the way to inject the dependency
Oftentimes if we want to provide a singleton service we might use the
useClass option as in:
In the case above, we’re using the class
SpotifyService as the token in the DI system. The
useClass option tells Angular to create an instance of
SpotifyService and reuse that instance whenever the
SpotifyService injection is requested (e.g. maintain a Singleton).
One problem with us using this method is that we don’t want Angular to create our store – we did it ourselves above with
createStore. We just want to use the
store we’ve already created.
To do this we’ll use the
useValue option of
provide. We’ve done this before with configurable values like
API_URL:
The one thing we have left to figure out is what token we want to use to inject. Our
store is of type
Store<AppState>:
export function createAppStore(): Store<AppState> { return createStore<AppState>( reducer, compose(devtools) ); } export const appStoreProviders = [ { provide: AppStore, useFactory: createAppStore } ];
Store is an interface, not a class and, unfortunately, we can’t use interfaces as a dependency injection key.
If you’re interested in why we can’t use an interface as a DI key, it’s because TypeScript interfaces are removed after compilation and not available at runtime.
If you’d like to read more, see here, here, and here.
This means we need to create our own token that we’ll use for injecting the store. Thankfully, Angular makes this easy to do. Let’s create this token in it’s own file so that way we can
import it from anywhere in our application;
export const AppStore = new InjectionToken('App.store');
Here we have created a
const AppStore which uses the
OpaqueToken class from Angular.
OpaqueToken is a better choice than injecting a string directly because it helps us avoid collisions.
Now we can use this token
AppStore with
provide. Let’s do that now.
Bootstrapping the App
Back in
app.module.ts, let’s create the
NgModule we’ll use to bootstrap our app:
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { FormsModule } from '@angular/forms'; import { HttpModule } from '@angular/http'; import { appStoreProviders } from './app.store'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, FormsModule, HttpModule ], providers: [ appStoreProviders ], bootstrap: [AppComponent] }) export class AppModule { }
Now we are able to get a reference to our Redux store anywhere in our app by injecting
AppStore. The place we need it most now is our
AppComponent.
Notice that we exported the function
appStoreProvidersfrom
app.store.tsand then used that function in
providers. Why not use the
{ provide: ..., useFactory: ... }syntax directly? The answer is related to AOT – if we want to ahead-of-time compile a provider that uses a function, we must first export is as a function from another module.
The
AppComponent
With our setup out of the way, we can start creating our component that actually displays the counter to the user and provides buttons for the user to change the state.
imports
Let’s start by looking at the imports:
import { Component, Inject } from '@angular/core'; import { Store } from 'redux'; import { AppStore } from './app.store'; import { AppState } from './app.state'; import * as CounterActions from './counter.actions';
We import
Store from Redux as well as our injector token
AppStore, which will get us a reference to the singleton instance of our store. We also import the
AppState type, which helps us know the structure of the central state.
Lastly, we import our action creators with
* as CounterActions. This syntax will let us call
CounterActions.increment() to create an
INCREMENT action.
The template
Let’s look at the template of our
AppComponent.
In this chapter we are adding some style using the CSS framework Bootstrap
<div class="row"> <div class="col-sm-6 col-md-4"> <div class="thumbnail"> <div class="caption"> <h3>Counter</h3> <p>Custom Store</p> <p> The counter value is: <b>{{ counter }}</b> </p> <p> <button (click)="increment()" class="btn btn-primary"> Increment </button> <button (click)="decrement()" class="btn btn-default"> Decrement </button> </p> </div> </div> </div> </div>
The three things to note here are that we’re:
- displaying the value of the counter in
{{ counter }}
- calling the
increment()function in a button and
- calling the
decrement()function in a button.
The
constructor
Remember that we need this component depends on the
Store, so we need to inject it in the constructor. This is how we use our custom
AppStore token to inject a dependency:
import { Component, Inject } from '@angular/core'; import { Store } from 'redux'; import { AppStore } from './app.store'; import { AppState } from './app.state'; import * as CounterActions from './counter.actions'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { counter: number; constructor(@Inject(AppStore) private store: Store<AppState>) { store.subscribe(() => this.readState()); this.readState(); } readState() { const state: AppState = this.store.getState() as AppState; this.counter = state.counter; } increment() { this.store.dispatch(CounterActions.increment()); } decrement() { this.store.dispatch(CounterActions.decrement()); } }
We use the
@Inject decorator to inject
AppStore – notice that we define the type of the variable
store to
Store<AppState>. Having a different injection token than the type of the dependency injected is a little different than when we use the class as the injection token (and Angular infers what to inject).
We set the
store to an instance variable (with
private store). Now that we have the store we can listen for changes. Here we call
store.subscribe and call
this.readState(), which we define below.
The store will call
subscribe only when a new action is dispatched, so in this case we need to make sure we manually call
readState at least once to ensure that our component gets the initial data.
The method
readState reads from our store and updates
this.counter to the current value. Because
this.counter is a property on this class and bound in the view, Angular will detect when it changes and re-render this component.
We define two helper methods:
increment and
decrement, each of which dispatch their respective actions to the store.
Putting It All Together
Try it out!
cd code/redux/redux-chat/redux-counter npm install npm start open
Congratulations! You’ve created your first Angular and Redux app!
What’s Next
Now that we’ve built a basic app using Redux and Angular, we should try building a more complicated app. When we build bigger apps we encounter new challenges like:
- How do we combine reducers?
- How do we extract data from different branches of the state?
- How should we organize our Redux code?
The next step is to build an intermediate Redux chat app. The code is open-source here and we go over how to build it step-by-step in the ng-book Intermediate Redux Chapter. If you found this book helpful, go grab a copy – you’ll become an Angular expert in no time.

Windows Terminal Preview 1910 Release
Kayla
Another update to the Windows Terminal has just been released! As always, you can download the Terminal from the Microsoft Store, the Microsoft Store for Business, and GitHub.
👉 Note: In the About popup within the Terminal, this version will appear as v0.6.
Updated UI
The Terminal now has even better tabs! The WinUI TabView used in the Terminal has been updated to version 2.2. This version has better color contrast, rounded corners on the dropdown, and tab separators. Also, when too many tabs fill the screen, you can now scroll through them with buttons!
Dynamic Profiles
Windows Terminal now automatically detects any Windows Subsystem for Linux (WSL) distribution installed on your machine along with PowerShell Core. If you install any of these after this update of the Terminal, they will appear in your profiles.json file!
👉 Note: If you don’t want a profile to appear in your dropdown, you can set
"hidden" to
true in your profiles.json file.
"hidden": true
Cascading Settings
The Terminal now has an improved settings model! It ships with a defaults.json file with all of the default settings included. If you’d like to see what’s included in the default settings file, you can hold down the
Alt key and click on the settings button in the dropdown menu. This file is an auto-generated file and changes made to the file are ignored and overwritten. Your own profiles.json file is where you can add as many custom settings as you’d like. 😊 If you’d like to reset your settings, Scott Hanselman (@shanselman) has written an excellent blog post on how to do just that!
If you add a new profile, scheme, key binding, or global setting in your profiles.json, it’ll be treated as an added setting. If you create a new profile whose GUID matches an existing one, then your new profile will override the old one. If there is a default key binding included in the defaults.json file that you would like to free up, you can set that key binding to
null in your profiles.json.
{
"command": null, "keys": ["ctrl+shift+w"]
}
New Launch Settings
You can now set the Terminal to launch as maximized or set its initial position! Setting the Terminal to launch as maximized can be done by adding the global setting
"launchMode". This setting accepts either
"default" or
"maximized".
"launchMode": "maximized"
If you’d like to set the Terminal’s initial position, you can add
"initialPosition" as a global setting. This property accepts a string with the X and Y coordinates separated by a comma. For example, if you’d like the Terminal to launch at the top left of your primary screen, you’d add the following to your profiles.json:
"initialPosition": "0,0"
👉 Note: If you’re using multiple monitors and would like to set the Terminal to launch to the left or above your primary monitor, you will have to use negative coordinates.
Bug Fixes
🐛 You can now double-click on the tab bar to maximize the window!
🐛 One of the main bugs causing newline issues with copy and paste has been fixed!
🐛 HTML copy doesn’t leave the clipboard open anymore!
🐛 You can now use font names longer than 32 characters!
🐛 There is no longer text corruption when running two tabs at the same time!
🐛 General stability improvements (less crashes)!

Nice! Hotly anticipating tab splitting…
Can we run this on Windows server 2016 yet?
How do you contribute?
The terminal output performance is still about 10 times slower than the Windows console, at least on my machine.
Is this normal behaviour, and if so, are there some plans to improve it?
The questions I have… Does vim and emacs work well in terminal mode? Does it support xterm like mouse extensions? Any thoughts on regis , tnex or tex4014 graphic support? One click cut and paste?
Is there any way to open a new tab in the same directory?
‘Settings’ opens the auto-generated profiles.json with: ‘// THIS IS AN AUTO-GENERATED FILE! Changes to this file will be ignored.’ on the first line. This is the file in AppData. Why doesn’t ‘Settings’ open my editable profiles.json by default?
Command line parameters, please! Really need this a while lot.
I’m loving the improvements, but the Copy/Paste bug that remains is still killing me.
Try copy/pasting any multi-line text with indentation from any text editor in Windows to the Terminal running Ubuntu. For a good example, try pasting this into an editor in the terminal (emacs, vim, nano), or even better, the ipython shell:
from time import sleep
for x in range(0, 5):
sleep(x)
y = True
while y:
print(“I slept for a few seconds.”)
y = False
You’ll see what I mean… it never gets to the y = False. This is the the bug that continues to keep me on PuTTy more than any other.
